* Makefile.am, configure.ac, posix/Makefile.am, wrapup/Makefile.am:
Move Ada support code that is untestable from the Standard RTEMS Test
Suite into its own directory. All code in score, posix, rtems, and
sapi should be testable by the Standard RTEMS Test Suites. It was
buried under POSIX before so this should be a clearer location
anyway.
* libgnat/.cvsignore, libgnat/Makefile.am, libgnat/ada_intrsupp.c,
libgnat/adasupp.c: New files.
* posix/src/ada_intrsupp.c, posix/src/adasupp.c: Removed.
