QEMU by itself can be built outside of its source directory. With the qemu repository being separate from the hypervisor/tools one it seems to make sense to make use of this feature, but doing so requires a couple of adjustments to the Xen changes to it. Basically, if CONFIG_QEMU is found to indicate an existing directory, this directory will be used rather than cloning the git repo into the build tree. The patch contains QEMU and tools/stubdom changes together for the moment (with QEMU supposed to be residing in qemu/). For applying this would need to be split.
