    Add extern_protected_data and set it for x86

    With copy relocation, address of protected data defined in the shared
    library may be external.  This patch adds extern_protected_data and
    changes _bfd_elf_symbol_refs_local_p to return false for protected data
    if extern_protected_data is true.
