Then that needs a comment.

Also, I suggest looking into how other packages that need to force clang
do it.  Setting PKGSRC_COMPILER seems wrong.

That's a bug in meson then :-)

But seriously, pkgsrc uses CFLAGS.  If we need a translation layer from
what's in CFLAGS to some meson options, that belongs in
devel/meson/build.mk.
