Oh no! I really need to get better about checking the bug tracker to see
if someone else has already worked through changes I'm thinking of.

I tried a bit of pkg-config hackery/trickery for a bunch of the
packages, even messing with the meson cross definitions file, but it
turned out that pkg-config-for-build did the exact wrapping that was
needed AND it provided a symlink from (pkg-config-for-target) to
"pkg-config", which was what meson needed.

I'll cherry-pick the commits over to core-updates and then do some of
the fixups to make everything cleaner.
