qemu upstream uses git submodules. git archive does not work with git submodules (and could not work properly with them, because this is one of the many things it is inherently impossible to do correctly with git submodules). qemu upstream have worked around this by providing a rather scary shell script which attempts to do roughly the right thing. It's close enough that we can use it with only minor precautions. Unfortunately this does mean that `mktarball' now executes the qemu source code it was using, rather than merely shuffling it about, as it did previously. I think this is a less bad ill than copying (and, effectively, forking) the scary script.
