Patch ("FIX: no_cpu/no_bsp") from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:

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

make/target.cfg.in
