I don't think PACKAGECONFIG will help unless we have a way to explicitly
disable or enable the dependency with waf, otherwise it'd still be
non-deterministic. But I think that would be ideal, that's how we handle
these things in autoconf, add an argument to let us explicitly
enable/disable it. Hopefully someone else on the list knows enough about
waf to be able to do so.
