My main requirement is that I don't have to change anything when making 
a tarball release.

kvm releases carry a KVM_VERSION file that could be used to disable werror.

It's a good point about the stable branch though.  I don't know the best 
way to deal with that.  Disabling werror more than we could is certainly 
better than enabling it more than we should though.
