    tail recursion in _bfd_elf_link_hide_symbol
    
    We can clear the flags first if no backend hide_symbol function tests
    or sets them, which is true.
    
            * elflink.c (_bfd_elf_link_hide_symbol): Clear flags before
            calling elf_backend_hide_symbol, to enable tail recursion.
