Joel Sherrill 70810dcd89 Patches rtems-rc-20000204-0.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>
that contains:

* Removes remaining (now illegal) references to $(SRC) from a couple of
  Makefile.ams
* Removes duplicate AC_CONFIG_SUBDIRS macro from c/configure.in
* Moves ENABLE_LIBCDIR into RTEMS_PROG_C[C|XX]_FOR_TARGET (hides LIBCDIR
  from most configure scripts, i.e. LIBCDIR becomes less visible)
* Adds RTEMS_PROG_C[C|XX]_FOR_TARGET and RTEMS_CANONICALIZE_TOOLS to
  libbsp/*/configure.ins (A minor bug in previous implementations, which
  only has an impact when switching to GNU/Cygnus canonicalization)
* Cleans up several bogus comments.
* Removes MKLIB
* Switches the version number to 4.5.0 (for testing version number
  handling)
