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.
