Actually I thought about this and FFmpeg should link to pthread if
x264 (or any other dependency) is linking to pthread, even if we don't
want to use thread s in FFmpeg. This is already happening behind the
curtains by the linking system when x264 is linked dynamically: when
libavcodec.so is loaded so is libx264.so, and then in turn
libpthread.so. Therefore the same should happen when linking

Apparently other dependencies also require pthread: libschroedinger,
libxvidcore. And probably more depending on how they are compiled.
