So the recent code in qemu cvs has problem powerpc. So what I have done
is mainly work around this in the build system, by creating
ppcemb_kvm-sofmmu target. Along with this is a fake-exec.c that stubs
out the functions that are no longer defined (something done by Anthony
Liguori attempting to fix qemu_cvs). What do folks think about this
approach, for us all we really need is a qemu that is not built with tcg
dependency.
