By default, RTEMS is built using arguments and build rules which are
compatible with gcc 2.7.2.2. This requires that the user specify
the location of the Standard C Library with the --enable-libcdir
option. If using a gcc which supports the -specs option, then
the --enable-gcc28 option may be used to enable this feature.
