Should fix following error building gcc for ppc7450:

/tmp/ccmfQBT9.s:5197: Error: Unrecognized opcode: `lvx'
make[2]: *** [libgcc/./unwind-dw2.o] Error 1
make[2]: Leaving directory `build-gcc-core/gcc'
make[1]: *** [stmp-multilib] Error 2
make[1]: Leaving directory `build-gcc-core/gcc'
make: *** [all-gcc] Error 2

(I'm not so sure about the unconditional -many it sends to binutils;
that seems redundant?)

Branch: hammer-3_3-branch
Changes since 1.234.2.28: +15 -11 lines

	* config/rs6000/rs6000.h (ASM_CPU_SPEC): Handle -mpowerpc64 and -mcpu
	for power5 and rs64a.  Correct condition for default.  Correct power3,
	620, 630, 7400, 7450, G4, 970 and G5 -mcpu entries.  Add -many.
