powerpc: fix compiling CONFIG_PPC_TRANSACTIONAL_MEM when CONFIG_ALTIVEC=n
We can't compile a kernel with CONFIG_ALTIVEC=n when CONFIG_PPC_TRANSACTIONAL_MEM=y. We currently get: arch/powerpc/kernel/tm.S:320: Error: unsupported relocation against THREAD_VSCR arch/powerpc/kernel/tm.S:323: Error: unsupported relocation against THREAD_VR0 arch/powerpc/kernel/tm.S:323: Error: unsupported relocation against THREAD_VR0 etc. The below fixes this with a sprinkling of #ifdefs.
