Ah, yeah, you've reminded me.  So this appears in a number of places.
We basically have to have fdt support for the pseries platform.
What's the right way to make the whole machine definition conditional

Incidentally, can I suggest it might be a good idea to include libfdt
in the qemu tree and make it always-on instead of configurable.
