Thank you very much for the information and for the patch.

Given our freeze, I can add m68k to the list of architectures for those
build-deps, but I don't think we should apply Joey's patch for now.  But
let's let 10.20230126 migrate to testing first.  I've committed the
change to git; please remind me if I don't upload it a couple of days
from now.
