    Fix commit 980aa3e6

    Commit 980aa3e6 was supposed to cure dyn_reloc counting problems, but
    did the opposite.  For PIC we count two types of dyn_reloc, those on
    pc-relative relocs, and the total.  If a sym needs pc-relative dyn
    relocs then all the relocs are dynamic.  If not, then only those that
    are must_be_dyn_reloc are dynamic.

        PR 20519
        * elf64-ppc.c (pc_dynrelocs): New function.
        (ppc64_elf_relocate_section): Use it and must_be_dyn_reloc to
        handle pic dynamic relocs.
