Unless Aurelien speaks up and says that it is still maintained, I'd say
we add a big fat "ia is deprecated and going to be removed" warning to
the configure script once we left the freeze state. If nobody then
speaks up within the next two or three releases of QEMU, we remove the
ia64 support from QEMU.
