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.

Centralize the selection of codec compilation flags to codec.make
to avoid having to duplicate the per cpu selection logic and the
build rule in the individual codec lib make files and make tweaking
easier.
The two special cases, libmad and libspeex were left alone.
I plan to introduce a var for arm generation so that appropriate flags
can be selected per generation as benchmarking results have shown that
different arm arches might have different optimal flags.

Retune codec compiler optimizations with new compiler. Overall speedup with aac and flac getting big speedups.
