PR22431, powerpc64 ld segfault when .plt discarded
The fix for the PR is to not use input_section->output_section->owner
to get to the output bfd, but use the output bfd directly since it is
available nowadays in struct bfd_link_info.
I thought it worth warning when non-empty dynamic sections are
discarded too, which meant a tweak to one of the ld tests to avoid the
warning.

PR 22431
* elf64-ppc.c (ppc64_elf_size_dynamic_sections): Warn on discarding
non-empty dynamic section.
(ppc_build_one_stub): Take elf_gp from output bfd, not output
section owner.
(ppc_size_one_stub, ppc64_elf_next_toc_section): Likewise.
ld/
* testsuite/ld-elf/note-3.t: Don't discard .got.
