In the Ubuntu packaging I moved to not build qemu from Xen to just depend on the 
qemu package (which should be the same) at least for x86.
Since I have no Arm hw on my own, all the arm builds are more of a theoretical 
exercise (no feedback from anyone actually trying).
This sounds like I should (again) depend on a qemu-system-x86, even for the Arm 
packages. Is that right?
