This part is fixed in experimental, by modifying the patches that
introduced the use of pkg-config rather than adding a new one
(loosely based on what you contributed to quakespasm).

Yes. Game developers and their artisanal hand-crafted build systems :'-(

Thanks, I'll apply the rest (or something very similar) in the next
upload.

I know ioquake3 and yquake2 also need similar treatment, and they're in
my queue, so don't prioritize writing patches for those (ioquake3 also
can't currently cross-compile because opusfile isn't multiarch-friendly).
