gcc: Drop useless objc change from r260311.

Browse Source 
Among some of the objc changes from Apple that crept into r260311,
Radar 5355344 is incomplete and is not used since we don't carry
ObjC in the base system.

The dead code seems to have caused issues in some Tinderboxes so
get rid of it altogether.
