PowerPC ld segfault on script discarding dynamic sections
bfd/
* elf64-ppc.c (ppc64_elf_finish_dynamic_sections): Don't segfault
on .got or .plt output section being discarded by script.
* elf32-ppc.c (ppc_elf_finish_dynamic_sections): Likewise. Move
vxworks splt temp.
gold/
* powerpc.cc (Target_powerpc::make_iplt_section): Check that
output_section exists before attempting add_output_section_data.
(Target_powerpc::make_brlt_section): Likewise.
