This patch adds powerpc host support to the CONFIG_MMU_MAP patch
written by Piotrek. My patch should be applied on top of
v1-part[1-3].patch.gz. I have only tested the code with a x86 guest on
a ppc host running Linux - someone, please test on a host running OSX.
Segfaults for me on 10.3.7 after adjusting the assembler code and some
C to compile on this machine.

Hard to tell why, but code_gen_buffer contains only zeros after a
few iterations of cpu_x86_exec ().
Any idea how to debug this?
