Further testing suggests we either going to need a whitelist or a
blacklist for this :/

The key places people get bitten are eglibc and gcc so those should be
straight forward to test, the question is how widely to deploy this
initially. I think the mechanism is good, its now just a question of the
implementation detail.

FWIW, libgpg-error fails with checksum issues (checksumming a generated
file?!) and libtool has issues about cleaning directories that have
makefiles that were never generated...
