    ELF: Hide symbols defined in discarded input sections

    When assigning symbol version, we should hide debug symbols defined in
    discarded sections from IR objects so that they can be removed later.

        * elflink.c (_bfd_elf_link_assign_sym_version): Hide symbols
        defined in discarded input sections.
