* elflink.c (_bfd_elf_update_dynamic_flags): New.
(_bfd_elf_merge_symbol): Update both real and indirect symbol
dynamic flags.
(_bfd_elf_add_default_symbol): Make the real symbol dynamic if
the indirect symbol is defined in a shared library.
(elf_link_add_object_symbols): Likewise. If the indirect
symbol has been forced local, don't make the real symbol
dynamic.
(elf_link_check_versioned_symbol): Check indirect symbol.
(elf_link_output_extsym): Use real symbol definition when
reporting indirect symbol error. Check version info for
dynamic versioned symbol.
