We are *not* going down this route. We should fix the problematic .pc
files which are by definition broken if they're doing this, not start
mangling the .pc files.

The binconfig class is near unmaintainable due to these kinds of
problems, we have no idea which things we need to map and so on. With
pkgconfig, we used to have this madness, we got rid of most of it with
the inclusion of sysroot support in pkgconfig itself.

Cheers,
