I needed some new build-deps (pixman) but then it appeared to, yes.

I'm in favour of moving the --cpu out from under the
IOEMU_CONFIGURE_CROSS and into the normal configure rune. It should be
harmless for native builds and will ensure that cross builds don't
regress again. Maybe that is more complex with the qemu-trad side of
things?
