libmusicbrainz: revert the dso_linking_change patch as the new linker fixes it
The newer binutils recipe of version 2.21 has a fix for ld which avoids an
issue where weak symbols like pthread_cancel were causing linking to fail when
--no-add-as-needed parameter was passed to ld.
See more information here: http://bugs.debian.org/591405
This makes some of the fixes for breakage after gcc dso linking change
unnecessary and this is one of them.
