I'm updating the OpenPower firmware builds to use 2016.05 and came
across Stewarts patch in our tree. It would be good to get a fix
upstream.

Would you take a patch to update the autotools generated files in
fakeroot? This way we can build our firmware on the systems that they
run on, without anyone having to spend the extra time building.

Cheers,

Joel
