I've tested this with XEN_RELEASE set to 4.5 and 4.6, and it builds just
fine.  The #define is just ignored, since neither Xen nor qemu in the
4.5 and 4.6 branches know anything about it.

If part of our goal is to be a repository of the canonical way to build
things, though, perhaps it would be better to have the extra flags be
conditional on the value of XEN_RELEASE.
