I'm trying to reproduce this in our docker images (all x86_64 based) but
can't reproduce.
./configure shows:
KVM support yes
but in "sysemu/kvm.h" CONFIG_KVM_IS_POSSIBLE is not defined
I can see CONFIG_KVM defined, but no NEED_CPU_H.

I don't have native ppc64le to build, do you know if it is possible to
cross-compile enabling kvm? It seems I have the correct Linux headers, I
wonder if this isn't a ./configure test which disable the kvm cross-build.
