KVM compile fails on s390x

[Robin Atwood <robin@binro.org>]

I guess I am doing something very dumb, but when I try to compile kvm-72 on 
z900 architecture (actually Hercules) I immediately get a compile error:

Obviously some s390-specific equates are missing but I can't find any options 
to enable them and the arch seems correctly detected. The kernel is 2.6.26.
