Temporary workaround for ppc on ppc

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. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6967 c046a42c-6fe2-441c-8c8c-71466251a162
