This is the cut down version of the earlier series omitting unfinished
patches that I plan to rework later and rebased to Mark's qemu-macppc
branch. Compared to v7 the only change is the cast to (target_ulong)
from (uint32_t) as requested by Mark in patch 1.

FWIW the reason for suggesting the cast to target_ulong is so that the same code works for both qemu-system-ppc and qemu-system-ppc64. For qemu-system-ppc that should correctly drop the sign extension from 32-bit, whilst still allowing someone to load a 64-bit ELF into qemu-system-ppc64 if requested.

Can you confirm that the sign extension behaviour is still correct for both qemu-system-ppc and qemu-system-ppc64? If so I'm happy to give it a R-B tag.
