If you do this...

you don't need this.

Basically that's band aid, but I could live with it for now. A cleaner
approach would be to push the dummy type into (qemu-)kvm.h, ie. the file
responsible for importing the kernel headers in the USE_KVM/CONFIG_KVM case.
Note that qemu-kvm still breaks in the non-kvm build for other reasons
here. I wanted to look into this but got detracted.
