This qemu-for-american-fuzzy-lop package doesn't inherit from anything.
My goal was to completely separate it from the "real" QEMU package so
that we can ignore about it and let whoever is interesting in AFL take
care of it. It wouldn't be a problem to inherit these fields, but
instead I will edit them to describe what this package is for.
