Problem seems to be that signal.h is pulling in a bunch of ppc
headers which expose elf_greg_t, R_PPC_* and PPC_FEATURE_*.

Subject: [PATCH] Fix ppc-softmmu kvm-disabled build
This gets ppc-softmmu building when KVM is not enabled. It may be enough to get
it working with KVM enabled but I haven't checked.
