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
