This will break if QEMU_TAG is pointing to any commit that is more than
one commit away from a branch or tag in the source repository. In order
to allow using older xen repositories, this requires that every update
to QEMU_TAG in xen-*.hg also add a tag or branch to the git repository.

It would be nice if you could use git clone --branch $(QEMU_TAG)
but this is not supported when $(QEMU_TAG) is a commit ID.
