    x86: Don't set eh->local_ref to 1 for linker defined symbols

    Since symbols created by HIDDEN and PROVIDE_HIDDEN assignments in
    linker script may be marked as defined, but not hidden, we can't
    set eh->local_ref to 1 in _bfd_x86_elf_link_symbol_references_local.

    Also R_386_GOT32X should be handled as just like R_386_GOT32 when
    relocating a section.  The input R_386_GOT32X relocations, which
    can be relaxed, should have been converted to R_386_PC32, R_386_32
    or R_386_GOTOFF.


        PR ld/23189
        * elf32-i386.c (elf_i386_relocate_section): Handle R_386_GOT32X
        like R_386_GOT32.
        * elfxx-x86.c (_bfd_x86_elf_link_symbol_references_local): Don't
        set eh->local_ref to 1 for linker defined symbols.
