I think having separate flags would just be annoying. Lucas
redistribution is in no sense "official" in any way, and what if
someone else comes up with another re-package of the same thing?
The key information here is, upstream libmfx does not actually have a
pkg-config file, that some re-distributions add one is nice and all,
and we can use that if present, but we should also be able to use the
upstream variant which does not come with one at all.
