    PR26655, Power10 libstdc++.so R_PPC64_NONE dynamic relocs

    Some of the powerpc64 code editing functions are better run after
    dynamic symbols have stabilised in order to make proper decisions
    based on SYMBOL_REFERENCES_LOCAL.  The dynamic symbols are processed
    early in bfd_elf_size_dynamic_sections, before the backend
    always_size_sections function is called.

    One function, ppc64_elf_tls_setup must run before
    bfd_elf_size_dynamic_sections because it changes dynamic symbols.
    ppc64_elf_edit_opd and ppc64_elf_inline_plt can run early or late, I
    think.  ppc64_elf_tls_optimize and ppc64_elf_edit_toc are better run
    later.

    So this patch arranges to call some edit functions later via
    always_size_sections.
