FWIW, even if both clang and GCC default to C++ >= 11 now, clang makes 
errors out of a few things that GCC only throws warnings about.

In any case, the C++11 issues in libmfx should be fixed in upstream git 
master now, so you could drop this setting altogether by updating the 
libmfx version - I pushed such a commit.
