build system: completely autodetect target cpu architecture.
The existing ARCH Makefile variable is exported to the C code as well.
Additionally the version (arm-only for now) is detected as well. This
allows to for complete autodetection, i.e. that optimized ASM is picked up
if determined by preprocessor (CPU_ARM, etc).
Building a sim/raaa on a arm host will now automatically generate a arm
optmized build like we have for native targets.
