    PowerPC64 abort due to dynamic relocs on hidden undefweak

    ppc64_elf_relocate_section lacked a check which meant that it emitted
    dynamic relocs against a hidden undefweak symbol for which no dynamic
    relocs had been allocated.

        * elf64-ppc.c (ppc64_elf_relocate_section): Add missing
        dyn_relocs check.
