Temporary workaround for ppc on ppc

Browse Source 
target-ppc/translate.c puts values of type opcode_t into .opcodes
section, using GCC extension to do so, and hoping that this will make
them appear contiguously and in the source order in the resulting
executable. This assumption is not safe and is known to be violated
with certain versions of GCC, certain flags passed to it and on
certain platforms (gcc 4.3.0, -O and PPC/PPC64 for instance)

The workaround consists of adding -fno-unit-at-a-time to the list of
GCC command line options while building PPC translate.o on a PPC.
