This is a wrong-code bug, identified by newer Darwin linkers, tested
on x86_64, i686 and aarch64 Darwin, pushed to trunk, backports to open
branches to follow, thanks,

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.
