Patches rtems-rc-20000204-0.diff from Ralf Corsepius <corsepiu@…>
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)
  • Property mode set to 100644
