What would make the most sense logically to me is to use
qemu-system-aarch64 to launch an aarch64 machine and qemu-system-s390x
to launch an s390x machine (at least from an user perspective.) That
said, I haven't looked at this series yet, but it does sound like a good
idea in general regardless of how we plan to launch different arch guests.
