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. Change-Id: I0b35393f8fb3ebd20beaa9e7371fa57bf3782107
