    Darwin: Make metadata symbol lables linker-visible for GNU objc.
    
    Now we have shifted to using the same relocation mechanism as clang for
    objective-c typeinfo the static linker needs to have a linker-visible
    symbol for metadata names (this is only needed for GNU objective C, for
    NeXT the names are in separate sections).
    
    gcc/ChangeLog:
    
            * config/darwin.h
            (darwin_label_is_anonymous_local_objc_name): Make metadata names
            linker-visibile for GNU objective C.
