I'm afraid I still think this is a terrible idea. "Xen" isn't a CPU, and
"the binary is smaller" isn't IMHO sufficient justification for breaking
QEMU's basic structure of "target-* define target CPUs and we have
a lot of compile time constants which are specific to a CPU which
get defined there". How would you support a bigendian Xen CPU,
just to pick one example of where this falls down?
