fixes the segfault in libav's/ffmpeg's ff_imdct_calc

nautilus or soundconverter crash when loading a wma file, showing libgstffmpeg.so in the backtrace (sorry, didn't save it) as the source.

Some googling reveals this:
* http://us.generation-nt.com/answer/bug-635324-libavcodec52-crash-ff-imdct-calc-sse-help-204207951.html
* http://git.libav.org/?p=libav.git;a=commit;h=03ef9828b551fa9e91898d0f3c156d7c3fa11c92

And since gst-plugins-ffmpeg bundles libav/ffmpeg-0.6 the above patch also works when adjusting the paths (see attached patch).

After applying the patch nautilus and soundconverter work as expected.

Does this still apply to 0.10.13-r2 ?

should be fixed in gst-plugins-ffmpeg-0.10.13_p201211 (uses system ffmpeg and an upto date ffmpeg/libav)
