Yes, it is fixed in the second patch. But it is still needed after that.

Current versions of libavformat link directly to this symbol, and if the 
libavutil shared library is updated to a version without the symbol, the 
older libavformat will fail to load. So for distributions shipping libav* 
in separate packages, this is a must, unless we want them to always 
enforce all libav* from the exactly same build...
