I've been building mesa OOT for 2+ years, and I'm afraid that I've not hit
headers issues. If you can come up with some examples/how to, that'll be
appreciated.

There is some (re-)linking fun, when libtool 'inserts' -L/usr/lib prior to
-L/custom/prefix, but that will require a massive rewrite on our side :'(
