Check for a changed QEMU_TAG. If it has changed since last build, delete old
qemu sources and refetch with new QEMU_TAG.

Deleteing and recloning seems like an awfully big hammer. Can the same
not be achieved with a "git fetch origin" and a "git reset<tag>"?

I'm no git expert :-)
I just created an automated version of the currently supported "official" way
to handle this kind of problem (make distclean) without deleting everything.

I don't know if there are any nasty side effects possible with your proposal,
so it would be nice if someone with more git experience could set up a better
solution.
