1. Go back and try to build 13.3 using the same configure options, does
that still work?

2. Show us the actual build failures, "does not work" is not enough
information.

As far as that goes, 13.4 and later don't print that message at all.
We concluded it was just noise and that better style is to output
nothing unless there's a problem [1].  (This probably should have been
mentioned in the release notes, but it wasn't because the responsible
commit failed to say anything about it in its commit message.)

I grepped through your make log and I don't actually see any errors
or warnings; in particular, all the .pc files you mention seem to
be getting built as normal.  So I'm still confused as to where your
actual problem is.  Maybe things are going wrong at install, rather
than make?  Or at build of some other software that uses these
libraries?
