This set of changes is the build of what was required to convert to GNU autoconf. This is the first large step in allowing an RTEMS user to perform a one-tree build (per crossgcc FAQ) including RTEMS in the build process. With this change RTEMS is configured in built in the same style as the GNU tools, yet retains the basic structure of its traditional Makefiles (ala Tony Bennett). Jiri Gaisler (jgais@wd.estec.esa.nl) deserves (and received) a big thank you for doing this. There are still issues to be resolved but as of this commit, all target which can be built on a linux host have been using a modified version of the source Jiri submitted. This source was merged and most targets built in the tree before this commit. There are some issues which remain to be resolved but they are primarily related to host OS dependencies, script issues, the use of gawk for hack_specs, and the dependence on gcc snapshots. These will be resolved.

Patch from Emmanuel Raguet <raguet@crf.canon.fr> to add remote debug server and RPC support to RTEMS. Thanks. :) Email follows: Hello, For Xmas, here is the Remote Debugger on RTEMS ! Here are 2 patches for the Remote Debugger on RTEMS for pc386 from Linux host : - one for RTEMS it self, - one for GDB-4.17. 1/ RTEMS patch -------------- This patch adds 2 libraries : - a simplified SUN RPC library - the Remote Debugger library The configuration command is the following : ../rtems4/configure --target=i386-rtemself --enable-rtemsbsp=pc386 --enable-rdbg The SUN RPC library is built only if networking is set. The RDBG library is built if networking and enable-rdbg are set. The function used to initialize the debugger is : rtems_rdbg_initialize (); A special function has been created to force a task to be in a "debug" state : enterRdbg(). The use of this function is not mandatory. 2/ GDB-4.17 patch ----------------- This patch create a new RTEMS target for GDB-4.17. The configuration command is the following : ./configure --enable-shared --target=i386RTEMS To connect to a target, use : target rtems [your_site_address] Then, attach the target using : attach 1 And...

AC_PATH_PROG(CHMOD,chmod)
AC_PATH_PROG(SORT,sort)
Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>. Comments: * Added support for bsd "install" ($(BSDINSTALL)) to host.cfg.in, i.e. the standard "install" program that most packages (including automake) use. In Makefiles outside of rtems, "install" normally is referenced by $(INSTALL), but rtems already uses $(INSTALL) for install-if-change, hence I used $(BSDINSTALL) instead to keep up backward compatibility. * Removed references to @GREP@ etc. from host.cfg.in, as configure.in doesn't check for them (Minor cleanup). * Added installation flags INST*FLAGS to host.cfg.in, which should replace -m XXXX flags for installation calls. *Changes to gcc.cfg to enable it to build host programs from multiple sources files. Should not disturb existing sources, but neccessary. * There was a not-so-minor bug in the configuration files: "make install" and "make debug_install" don't work in all subdirectories!! I tried to fix this by adding "install" to MTARGETS in main.cfg, which seems to solve most of the problems. But there still seem to be rare (?) cases where "make debug_install" still seems to have problems. * Changes to many host related tool-Makefiles to demonstrate the abilities of INST*FLAGS, BSDINSTALL and the new rules in gcc.cfg. ..of cause ... but BSDINSTALL is THE standard method to install files in most program packages besides rtems. This part of the patch fixes some minor protection setting problems, but doesn't support TARGET_VARIANTS NOTE: I hope you will like the BSDINSTALL, INST*FLAGS stuff. It is a step to get rid of "install-if-change" and to rely on a more standard installation procedure. If you don't like BSDINSTALL, removing it from the patch isn't difficult- just grep for BSDINSTALL and replace BSDINSTALL with INSTALL or MKDIR. FINALLY: I still have another patch pending (well, not a complete patch yet, it's a partial patch to demonstrate the principle), which adds automatic rebuilding of files generated by autoconf/configure. At the moment I don't dare to submit it, because integrating this patch would require to modify all Makefile.ins because we'd need to add a new "include " line to each Makefile.in.

AC_PROG_INSTALL
Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>: 1. Rtems contains some perl scripts that use hard-coded paths to /usr/bin/perl or /usr/local/bin/perl I have already fixed these problems by adding some checks to configure.in. While doing this, I also cleaned up some more autoconf related problems for generating shell scripts. This patch might seem a bit scary to you, but I am quite confident it won't break something (I've been testing it for almost a week now, however it might introduce typos for a limited number configurations I don't have access to - But it shouldn't be a problem for you to test them :-). I expect to get this finished tonight, hence you will very likely have the patch when you get up tomorrow. Changes: * Check for PERL and disable all PERL scripts if perl wasn't found. * Generate all KSHELL-scripts with autoconf instead of make-script * Automatic dependency handling for autoconf generated KSHELL or PERL scripts (make/rtems.cfg) Notes: * this patch contains new files and deletes some other files. * The patch is relative to rtems-4.0.0-beta4 with my previous rtems-rc-981014-1.diff patch applied. Testing: I tested it with sh-rtems and posix under linux. Now all targets which are touched by this patch and which are not used while building for sh-rtems and posix still need to be tested. AFAIS, only the sparc/erc32 BSP should be affected by this criterion. And if you like to, you should also consider testing it on a Cygwin32 and a Solaris host for one arbitrary BSP.

This set of changes is the build of what was required to convert to GNU autoconf. This is the first large step in allowing an RTEMS user to perform a one-tree build (per crossgcc FAQ) including RTEMS in the build process. With this change RTEMS is configured in built in the same style as the GNU tools, yet retains the basic structure of its traditional Makefiles (ala Tony Bennett). Jiri Gaisler (jgais@wd.estec.esa.nl) deserves (and received) a big thank you for doing this. There are still issues to be resolved but as of this commit, all target which can be built on a linux host have been using a modified version of the source Jiri submitted. This source was merged and most targets built in the tree before this commit. There are some issues which remain to be resolved but they are primarily related to host OS dependencies, script issues, the use of gawk for hack_specs, and the dependence on gcc snapshots.

Monstrous patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>. I have made no attempt to divide the comments up and place them with just the appropriate files. Here is an excerpt from Ralf's email: Changes including comments on changes I made after cycling through all the targets: * Added ranlib support. Now all targets use "ranlib" instead of "ar -s" to build an index for a library. If ranlib isn't detected during configuration, check if ar -s is working and try "ar -s" instead of * Removed $(XXX_FOR_TARGET) from make/target.cfg.in, use $(XXX) instead now. * gcc-target-default.cfg: LINK_XXXX-defines reworked to solve the -l problem under posix (cf gcc-target-default.cfg) * rtems-glom replaced by Makefile-rules inside of the wrapup/Makefile.in that has been using rtems-glom until now. * Removed CCC and friends in gcc-target-default.cfg, as they have been breaking CXX support. * Removed CONFIG.$(TARGET_ARCH).CC lines from several custom/*.cfg files, because this is now set in custom/default.cfg. * Added aclocal/ar-s.m4, check whether "ar -s" is working * Added aclocal/cygwin.m4 and aclocal/exeext.m4. * Reworked aclocal/canonicalize-tools.m4: Added ar -s check; fixes for problems when XXX_FOR_TARGET is given via environment variables (didn't work for gcc until now), adding cygwin check, improved autoconf-cache handling. * Removed -l from make rule dependencies. LINK_LIBS is now allowed to contain -L and -l. LINK_OBJS and LINK_FILES must not contain -L or -l. gcc28 make-exe rules now link using $(LINK_OBJS) $(LINK_LIBS) => Almost all custom/*.cfg are modified. This is very likely to break something because of typos or having missed to edit a file. Open problems, known bugs, things I didn't do: * custom/p4000.cfg seems to be out of date and requires to be reviewed. (JRS NOTE: It is subordinate p4650 and p4600 -- both of which build ok after minor changes.) * custom/psim.cfg needs to be reviewed, I added some changes to it, I am insecure about. (JRS NOTE: psim had a minor problem endif/endef swapped but runs fine.) * rtems-glom.in can now be removed. * gcc*.cfg files "make depend" rules don't honor language specific flags (e.g CXXFLAGS is ignored for *.cc) - Nothing to worry about now, but may cause problems for hosts/targets not using gcc or rtems-add-ons that use external packages. * AFAIS, the no_bsp BSP can't be build anymore, i.e. configure refused to configure for it whatever I tried. * The toplevel and toplevel+1 README files are quite out-dated * cygwin.m4 isn't of much use for rtems. In most cases (cf. aclocal/*.m4) it is worked around by directly using $host_os. I think I'll remove it soon after the next snapshot * Before release the cygwin patch needs to be tested under cygwin. I may have broken/missed something (esp. the sed-pattern to convert \\ into / may be broken). * You should try to build/run the posix-BSP under solaris - I don't expect problems, but I am not 100% sure, esp. with regard to ranlib/ar -s. * You should consider to convert all make/compilers/*.cfg files into make/compilers/*.cfg.in files and let autoconf generate the *.cfg. This may help getting rid of some if/then/else statements and help hard-coding some defines into those files in future and shouldn't disturb now. * Not having installed libc.a/libm.a on a host may still break building rtems, esp. when using -disable-gcc28 as the gcc27-configuration scheme directly accesses libc.a and libm.a. The problem should not appear when using gcc28 because it references libc/libm only through -lc and -lm which may be static or dynamic (I didn't test this). * shgen is not yet included (I didn't yet have enough time to integrate it). * I know about a few more configure-probs (esp. cross-checking --enable-* flags). + warn/refuse to configure when --enable-libcdir and --enable-gcc28 are given. + force --enable-libcdir when --disable-gcc28 is given * Replaced KSHELL with @KSH@ in some shell scripts generated by configure.in. * Added a dependency to aclocal/*.m4 in the toplevel Makefile => configure and aclocal.m4 will now be rebuild when any aclocal/*.m4 file is changed * Some changes to aclocal/gcc-pipe.m4 and aclocal/gcc-specs.m4 * Replaced i[[3456]]86-unknown-freebsd2.[[12]] with i[[3456]]86-*freebsd2.* in configure.in, as I suppose there might exist a variety of valid vendors (2nd field of the name-tripple) * Disabled override MAKEFLAGS in toplevel Makefile.in - Potential side-effects are not really clear to me. * In mvme162.cfg, $(LINK_LIBS) is missing in the CC line in gcc28's make-exe rule (yet another one I missed to edit). Just append $(LINK_LIBS) to the "CC" line, like I hopefully did to ALL other custom/*.cfg files. * the problem with mvme162lx.cfg is a follow-up problem of the mvme162.cfg-bug. * mvme162/console and idp/console had variables named Buffer which conflicted with similarly named variables in some tests.

Now all targets use "ranlib" instead of "ar -s" to build an index for a library. If ranlib isn't detected during configuration, check if ar -s is working and try "ar -s" instead of * Removed $(XXX_FOR_TARGET) from make/target.cfg.in, use $(XXX) instead now. * gcc-target-default.cfg: LINK_XXXX-defines reworked to solve the -l problem under posix (cf gcc-target-default.cfg) * rtems-glom replaced by Makefile-rules inside of the wrapup/Makefile.in that has been using rtems-glom until now. * Removed CCC and friends in gcc-target-default.cfg, as they have been breaking CXX support. * Removed CONFIG.$(TARGET_ARCH).CC lines from several custom/*.cfg files, because this is now set in custom/default.cfg. * Added aclocal/ar-s.m4, check whether "ar -s" is working * Added aclocal/cygwin.m4 and aclocal/exeext.m4. * Reworked aclocal/canonicalize-tools.m4: Added ar -s check; fixes for problems when XXX_FOR_TARGET is given via environment variables (didn't work for gcc until now), adding cygwin check, improved autoconf-cache handling. * Removed -l from make rule dependencies. LINK_LIBS is now allowed to contain -L and -l. LINK_OBJS and LINK_FILES must not contain -L or -l. gcc28 make-exe rules now link using $(LINK_OBJS) $(LINK_LIBS) => Almost all custom/*.cfg are modified. This is very likely to break something because of typos or having missed to edit a file. Open problems, known bugs, things I didn't do: * custom/p4000.cfg seems to be out of date and requires to be reviewed. (JRS NOTE: It is subordinate p4650 and p4600 -- both of which build ok after minor changes.) * custom/psim.cfg needs to be reviewed, I added some changes to it, I am insecure about. (JRS NOTE: psim had a minor problem endif/endef swapped but runs fine.) * rtems-glom.in can now be removed. * gcc*.cfg files "make depend" rules don't honor language specific flags (e.g CXXFLAGS is ignored for *.cc) - Nothing to worry about now, but may cause problems for hosts/targets not using gcc or rtems-add-ons that use external packages. * AFAIS, the no_bsp BSP can't be build anymore, i.e. configure refused to configure for it whatever I tried. * The toplevel and toplevel+1 README files are quite out-dated * cygwin.m4 isn't of much use for rtems. In most cases (cf. aclocal/*.m4) it is worked around by directly using $host_os. I think I'll remove it soon after the next snapshot * Before release the cygwin patch needs to be tested under cygwin. I may have broken/missed something (esp. the sed-pattern to convert \\ into / may be broken). * You should try to build/run the posix-BSP under solaris - I don't expect problems, but I am not 100% sure, esp. with regard to ranlib/ar -s. * You should consider to convert all make/compilers/*.cfg files into make/compilers/*.cfg.in files and let autoconf generate the *.cfg. This may help getting rid of some if/then/else statements and help hard-coding some defines into those files in future and shouldn't disturb now. * Not having installed libc.a/libm.a on a host may still break building rtems, esp. when using -disable-gcc28 as the gcc27-configuration scheme directly accesses libc.a and libm.a. The problem should not appear when using gcc28 because it references libc/libm only through -lc and -lm which may be static or dynamic (I didn't test this). * shgen is not yet included (I didn't yet have enough time to integrate it). * I know about a few more configure-probs (esp. cross-checking --enable-* flags). + warn/refuse to configure when --enable-libcdir and --enable-gcc28 are given. + force --enable-libcdir when --disable-gcc28 is given * Replaced KSHELL with @KSH@ in some shell scripts generated by configure.in. * Added a dependency to aclocal/*.m4 in the toplevel Makefile => configure and aclocal.m4 will now be rebuild when any aclocal/*.m4 file is changed * Some changes to aclocal/gcc-pipe.m4 and aclocal/gcc-specs.m4 * Replaced i[[3456]]86-unknown-freebsd2.[[12]] with i[[3456]]86-*freebsd2.* in configure.in, as I suppose there might exist a variety of valid vendors (2nd field of the name-tripple) * Disabled override MAKEFLAGS in toplevel Makefile.in - Potential side-effects are not really clear to me. * In mvme162.cfg, $(LINK_LIBS) is missing in the CC line in gcc28's make-exe rule (yet another one I missed to edit). Just append $(LINK_LIBS) to the "CC" line, like I hopefully did to ALL other custom/*.cfg files. * the problem with mvme162lx.cfg is a follow-up problem of the mvme162.cfg-bug. * mvme162/console and idp/console had variables named Buffer which conflicted with similarly named variables in some tests.

A patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>: Here is another patch to hopefully enhance rtems' configuration. Motivation: Try to support other c-compilers besides gcc (I tried to build rtems under Solaris using sun's WSPro c-compiler). Here is a couple of small patches concerning the host compiler configuration, which fix/work-around the worst problems when using sun's WSPro c-compiler. Changes: * Replaced make/compilers/gcc.cfg with make/compilers/gcc.cfg.in, ie. gcc.cfg is generated by configure now. * Removed a line containing a hard-coded "gcc" from gcc.cfg (BUG-fix). * Add -g to host compiler flags only if configure reported -g to work * Add -Wall to host compiler flags only if configure reported that the host compiler is gcc (WSPro's cc chokes on -Wall). * Some modifications to make/Makefile.in * Adapted make/custom/default.cfg to the new location of gcc.cfg BTW, gcc.cfg/gcc.cfg.in seems to be full of unused code (DEBUG-VARIANTS etc.) which deserves to be cleaned up, IMO. IMO, a similar patch should be applied to gcc-target-default.cfg

Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>: 2. "make profile" doesn't work. It aborts when building host-tools for embedded targets. I didn't yet have enough time to fix this problem. AFAIS this problem is related to handling of LDFLAGS_PROFILE[|_V] in gcc.cfg.in. For host applications, we use gcc for linking host applications, too. With profiling enabled CFLAGS_PROFILE_V contains -pg and is used to compile, but LDFLAGS_PROFILE_V is empty, hence -pg will not be passed to the linker causing gcc to fail to link, because it can't resolve some symbols introduced by compiling with -pg. I am not sure if I can provide a patch for this - Ether it is trivial to fix or requires basic work on host configuration ;- Fixing this one was trivial - But hard to trace. LDFLAGS_PROFILE_V needs to contain the same flags as CFLAGS_PROFILE_V, if gcc is used for linking (What else should have been expected ?, :-). The same problem was present for *_DEBUG_V, but apparently wasn't noticed by anybody, because things didn't break, but were silently ignored. I fixed these problems by setting these flags in configure.in whenever gcc is reported to be the host-compiler. For non-gcc host compilers "make debug" and "make profile" now becomes the same as an ordinary "make". This is a hack and addressing this problen could be more sophisticated, but I don't think it gives much sense to support compile variants for any host program (Who will ever try to profile/debug host tools?). Therefore I don't think it's useful to invest more effort into this problem.

Update from Ralf Corsepius: Yep, I have a bunch of bug-fixes and additions pending (Yet another monster patch, ... I can hear you scream :-). 1) configure.in : one AC_CONFIG_HEADER(...) line too much. 5) configure.in: --enable-cpp should probably be renamed to --enable-cxx, as gnu-programs use "cxx" to specify C++ specific configure options, while cpp is used for the preprocessor (e.g egcs uses --with-cxx-includedir, autoconf internally uses $CXX),

RTEMS_CHECK_MAKEFILE(c/src/lib/libbsp/$bspcpudir$bspdir)
Patch from Eric VALETTE <valette@crf.canon.fr>: Here is a enhanced version of my previous patch. This patch enables to potentially share the new interrupt management code for all Intel targets (pc386, go32 and force386) bsp. Note : this patch is complete only for pc386. It still needs to be completed for go32 and force386. I carrefully checked that anything needed is in for force386 (only some function name changes for IDT manipulation and GDT segment manipulation). But anyway I will not be able to test any of theses targets...

Patch from Emmanuel Raguet <raguet@crf.canon.fr> to add remote debug server and RPC support to RTEMS. Thanks. :) Email follows: Hello, For Xmas, here is the Remote Debugger on RTEMS ! Here are 2 patches for the Remote Debugger on RTEMS for pc386 from Linux host : - one for RTEMS it self, - one for GDB-4.17. 1/ RTEMS patch -------------- This patch adds 2 libraries : - a simplified SUN RPC library - the Remote Debugger library The configuration command is the following : ../rtems4/configure --target=i386-rtemself --enable-rtemsbsp=pc386 --enable-rdbg The SUN RPC library is built only if networking is set. The RDBG library is built if networking and enable-rdbg are set. The function used to initialize the debugger is : rtems_rdbg_initialize (); A special function has been created to force a task to be in a "debug" state : enterRdbg(). The use of this function is not mandatory. 2/ GDB-4.17 patch ----------------- This patch create a new RTEMS target for GDB-4.17. The configuration command is the following : ./configure --enable-shared --target=i386RTEMS To connect to a target, use : target rtems [your_site_address] Then, attach the target using : attach 1 And... Debug ;) You can obtain the original GDB-4.17 on ftp://ftp.debian.org/debian/dists/stable/main/source/devel/gdb_4.17.orig.tar.gz This has been tested from a Debian 2.0.1 linux host.

A patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>: Here is another patch to hopefully enhance rtems' configuration. Motivation: Try to support other c-compilers besides gcc (I tried to build rtems under Solaris using sun's WSPro c-compiler). Here is a couple of small patches concerning the host compiler configuration, which fix/work-around the worst problems when using sun's WSPro c-compiler. Changes: * Replaced make/compilers/gcc.cfg with make/compilers/gcc.cfg.in, ie. gcc.cfg is generated by configure now. * Removed a line containing a hard-coded "gcc" from gcc.cfg (BUG-fix). * Add -g to host compiler flags only if configure reported -g to work * Add -Wall to host compiler flags only if configure reported that the host compiler is gcc (WSPro's cc chokes on -Wall). * Some modifications to make/Makefile.in * Adapted make/custom/default.cfg to the new location of gcc.cfg BTW, gcc.cfg/gcc.cfg.in seems to be full of unused code (DEBUG-VARIANTS etc.) which deserves to be cleaned up, IMO. IMO, a similar patch should be applied to gcc-target-default.cfg

Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>: 2. "make profile" doesn't work. It aborts when building host-tools for embedded targets. I didn't yet have enough time to fix this problem. AFAIS this problem is related to handling of LDFLAGS_PROFILE[|_V] in gcc.cfg.in. For host applications, we use gcc for linking host applications, too. With profiling enabled CFLAGS_PROFILE_V contains -pg and is used to compile, but LDFLAGS_PROFILE_V is empty, hence -pg will not be passed to the linker causing gcc to fail to link, because it can't resolve some symbols introduced by compiling with -pg. I am not sure if I can provide a patch for this - Ether it is trivial to fix or requires basic work on host configuration ;- Fixing this one was trivial - But hard to trace. LDFLAGS_PROFILE_V needs to contain the same flags as CFLAGS_PROFILE_V, if gcc is used for linking (What else should have been expected ?, :-). The same problem was present for *_DEBUG_V, but apparently wasn't noticed by anybody, because things didn't break, but were silently ignored. I fixed these problems by setting these flags in configure.in whenever gcc is reported to be the host-compiler. For non-gcc host compilers "make debug" and "make profile" now becomes the same as an ordinary "make". This is a hack and addressing this problen could be more sophisticated, but I don't think it gives much sense to support compile variants for any host program (Who will ever try to profile/debug host tools?). Therefore I don't think it's useful to invest more effort into this problem.

AC_CONFIG_HEADER(c/build-tools/src/config.h)
Serious cleanup to reduce the number of explicitly listed Makefiles, eliminated autoconf looking for commands which are unused, and reduce the number of Makefiles generated.

AC_OUTPUT(
Makefile
Update from Ralf Corsepius: Yep, I have a bunch of bug-fixes and additions pending (Yet another monster patch, ... I can hear you scream :-). 1) configure.in : one AC_CONFIG_HEADER(...) line too much. 5) configure.in: --enable-cpp should probably be renamed to --enable-cxx, as gnu-programs use "cxx" to specify C++ specific configure options, while cpp is used for the preprocessor (e.g egcs uses --with-cxx-includedir, autoconf internally uses $CXX),

A patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>: Here is another patch to hopefully enhance rtems' configuration. Motivation: Try to support other c-compilers besides gcc (I tried to build rtems under Solaris using sun's WSPro c-compiler). Here is a couple of small patches concerning the host compiler configuration, which fix/work-around the worst problems when using sun's WSPro c-compiler. Changes: * Replaced make/compilers/gcc.cfg with make/compilers/gcc.cfg.in, ie. gcc.cfg is generated by configure now. * Removed a line containing a hard-coded "gcc" from gcc.cfg (BUG-fix). * Add -g to host compiler flags only if configure reported -g to work * Add -Wall to host compiler flags only if configure reported that the host compiler is gcc (WSPro's cc chokes on -Wall). * Some modifications to make/Makefile.in * Adapted make/custom/default.cfg to the new location of gcc.cfg BTW, gcc.cfg/gcc.cfg.in seems to be full of unused code (DEBUG-VARIANTS etc.) which deserves to be cleaned up, IMO. IMO, a similar patch should be applied to gcc-target-default.cfg

Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de> heading toward automake: Notes: * I didn't yet touch the cpu subdirectory. I still need some time to think on how to handle them. * I probably will wait for the next snapshot before mailing more patches (I still have some pending), giving you a chance to apply them and me a chance to become target of the bullets which will probably be aimed at me after these modifications.

Fixed code for --disable-rtems-inlines so that it would complete configuration successfully. Added code to detect configuring macros and POSIX API at the same time. There is no macro implementation for the POSIX API.

Even more cleanup to make sure all the --enable/disable options avoid generating Makefiles where possible. Added code to make sure make/custom file and bsp directory exist for configured bsps. This code also accounts for "aliased" BSPs.

This set of changes is the build of what was required to convert to GNU autoconf. This is the first large step in allowing an RTEMS user to perform a one-tree build (per crossgcc FAQ) including RTEMS in the build process. With this change RTEMS is configured in built in the same style as the GNU tools, yet retains the basic structure of its traditional Makefiles (ala Tony Bennett). Jiri Gaisler (jgais@wd.estec.esa.nl) deserves (and received) a big thank you for doing this. There are still issues to be resolved but as of this commit, all target which can be built on a linux host have been using a modified version of the source Jiri submitted. This source was merged and most targets built in the tree before this commit. There are some issues which remain to be resolved but they are primarily related to host OS dependencies, script issues, the use of gawk for hack_specs, and the dependence on gcc snapshots. These will be resolved.
