Although orthogonal to the merging, I think this is a good change.
Furthermore, we already have modules installing .pc files to $datadir,
so people will have to deal with this type of change anyway. It's just
the right thing to do.

Do any of the proto packages install arch-specific headers? Certainly
there are arch-dependent definitions in the headers, but they go in
the same file with #ifdefs, right?
