We don't have to do it all at once though.  We could drop 32bit host
support now and figure how to handle qemu-system-i386 & friends later.

Just removing them would be one option.  Or have them check the
executable name and pick defaults based on that, so we can just symlink
qemu-system-ppc to qemu-system-ppc64.
