Gaah, check-package doesn't allow us from doing these nice hacks. We
could exclude this variable from the check-package check, but that's
really getting into doing a hack within the hack.

So I guess this really means we have to go with a per-package variable,
and a bit of logic in pkg-generic to collect these per-package
variables into a global one. Agreed?
