    PR28523, ld.bfd created undefined symbols on ppc64

    This patch removes any fake (linker created) function descriptor
    symbol if its code entry symbol isn't dynamic, to ensure bogus dynamic
    symbols are not created.  The change to func_desc_adjust requires that
    it be run only once, which means ppc64_elf_tls_setup can't call it for
    just a few selected symbols.

            PR 28523
            * elf64-ppc.c (func_desc_adjust): If a function entry sym is
            not dynamic and has no plt entry, hide any associated fake
            function descriptor symbol.
            (ppc64_elf_edit): Move func_desc_adjust iteration over syms to..
            (ppc64_elf_tls_setup): ..here.
