Some packages may not define custom cflags, in which case a simple

This change will be useful to get a valid include path that can be
used in library checks.
Is that at all a standard thing with pkgconfig?
From how I understand it, a .pc file could also call that variable
incdir, or whatever it likes?
I don't think incdir is a variable used in pc files. All the ones I've
seen use includedir, and that's what our helpers are already looking
for, too.
Never seen that done before anywhere.
See test_pkg_config_cpp()
This is to workaround the issue mentioned in
https://ffmpeg.org/pipermail/ffmpeg-devel/2021-September/286266.html
This value is already fetched by some of the configure helpers like i
said above, so I'm just exporting it as a per-library variable,
preventing the need to do custom calls to pkg-config like that patch
intends to.
