This is one of the ugly dependencies we've tried to ignore.

We basically assume if your build machine has graphics, you have the
devel headers/libs there and qemu will autodetect and include graphics
support. Equally, if your build machine doesn't, it just won't build
graphics support. In general most people seem happy with this even if
its imperfect.

Adding libxext-native upsets this balance a little...
