VLC Can't Play MKV Files With 9.1 / Clang

[John Schneider]

Hi,

Version 2.0.5,3 recently introduced a Makefile change to build with Clang
on 9.1+.  Unfortunately, I've found that MKV files will no longer play
after being built with Clang.  Commenting out this change and rebuilding
with base GCC results in MKV files playing just fine.
