FFmpeg's configure script already tried this option 
but clang / llvm does not support it;-(

The problem is even more visible with SDL, if you 
have it installed but disable the sdl output 
device (and ffplay), the final ffmpeg executable 
still depends on libsdl although the library does 
not resolve any symbol.

I don't know how to fix this.
