    Make Solaris global ABI syms STT_OBJECT and STV_PROTECTED
    
            PR 33177
            * emultempl/solaris2.em (elf_solaris_before_allocation): Make
            globals defined here STV_PROTECTED and STT_OBJECT.  Use
            elf_backend_hide_symbol rather that just setting forced_local
            for local ABI syms.
