Along the lines of what Andrew said, the probing done would then want
updating. Which in turn raises the need to properly know what to probe.
That said, from what I've read so far it's not the building of xen.efi
which would need disabling, but (as we already do for certain cases)
its building with debug info included (which in turn is now going to
require its stripping during the build process).
