Fix bad interaction between --relax and tls optimisation
Adding long-branch stubs for __tls_get_addr calls that are optimised
away is silly. It also causes assertion failures on newer object files
that use R_PPC_TLSGD and R_PPC_TLSLD marker relocs, and half-optimised
(ie. broken) code for older object files.
PR 16546
* elf32-ppc.c (ppc_elf_relax_section): Don't build long-branch
stubs for calls to __tls_get_addr that we know will later be
optimised away.

Enable ppc476 workaround for ld -r.
The Linux kernel builds modules using ld -r. These might need the
ppc476 workaround, so enable it for ld -r if sections have sufficient
alignment to tell location within a page.
bfd/
* elf32-ppc.c (ppc_elf_relax_section): Enable ppc476 workaround
for ld -r, when code sections are sufficiently aligned.
* elf32-ppc.h (struct ppc_elf_params): Delete pagesize. Add
pagesize_p2.
ld/
* emultempl/ppc32elf.em (pagesize): New static var.
(ppc_after_open_output): Set params.pagesize_p2 from pagesize.
(PARSE_AND_LIST_ARGS_CASES): Adjust to use pagesize.

PR15530, mark symbol in executables if it matches dynamic_list
For powerpc64 as HJ did earlier for other ELF targets, and a tidy.
PR gold/15530
* elf64-ppc.c (ppc64_elf_gc_mark_dynamic_ref): Support
--export-dynamic and --dynamic-list marking of symbols.
* elflink.c (bfd_elf_gc_mark_dynamic_ref_symbol): Reorder
cheap tests first.
