    Darwin, Objective-C/C++: Globalise protocol ref metadata symbols.
    
    Newer versions of the system static linker complain if Protocol reference
    lists are not introduced with a global symbol.
    
    gcc/ChangeLog:
    
            * config/darwin.cc (darwin_globalize_label): Handle Protocol
            references.
            (darwin_label_is_anonymous_local_objc_name): Likewise.
