    PR24704, Internal error building skiboot for powerpc64-linux-gnu

    While the skiboot linker script bears some culpability in this PR,
    it's also true that the GOT indirect to GOT relative optimisation for
    16-bit offsets isn't safe. At least, it isn't safe to remove the GOT
    entry based on distance between the GOT pointer and symbol calculated
    from the preliminary layout. So this patch removes that optimisation,
    and reduces the range allowed for 32-bit and 34-bit offsets.

     PR 24704
    bfd/
     * elf64-ppc.c (R_PPC64_GOT16_DS): Don't set has_gotrel.
     (ppc64_elf_edit_toc): Don't remove R_PPC64_GOT16_DS got entries.
     Reduce range of offsets allowed for other GOT relocs.
