This fixes the build in mingw-w64/Clang on MSYS2. It also disables the use of gnu_printf in Clang, which was what was causing most of the warnings. The Clang-compiled mpv binary appears to work, but there are no guarantees yet, since until now mpv has only been tested with mingw-w64/GCC on Windows. Fixes #3800
