Patch ("FIX: no_cpu/no_bsp") from Ralf Corsepius <corsepiu@…>:

This patch should fix the nastiest configuration bugs for no_cpu/no_bsp.

With this patch applied, configure --target=no_cpu-rtems now correctly
acknowledges its configuration, but later fails building when trying to
build libcsupport (I leave this problem for you :-).

Fixes/Changes?:

  • aclocal/canonicalize-target-name.m4: use RTEMS_CPU instead of target_cpu, switch to a native compiler setup if target = no_cpu*rtems, ie. implicitly use host=target (native) and RTEMS_CPU=no_cpu for --target=no_cpu*rtems.
  • add no_bsp/bsp_specs (Support -qrtems, -qrtems_debug; please check before adding :-)
  • Use RTEMS_CANONICALIZE_TARGET_CPU instead of AC_CANONICAL_SYSTEM in toplevel/configure.in
  • All references to $target_cpu in aclocal/*.m4, Makefile.ins and *.cfg files changed to RTEMS_CPU
  • bug fixes to exec/score/cpu/no_cpu/wrap (This part of the patch may result into patch rejections, because your recently posted patch may also have addressed this problem).

After applying this patch, please do:

cvs add c/src/lib/libbsp/no_cpu/no_bsp/bsp_specs
./autogen
