* elf32-ppc.c (apuinfo_set): New static var. (ppc_elf_begin_write_processing): Set it here, always create an APUinfo section if there were any in the inputs. (ppc_elf_write_section): Check apuinfo_set. (ppc_elf_final_write_processing): Likewise. ld/testsuite/ * ld-powerpc/apuinfo-nul.rd: New. * ld-powerpc/apuinfo-nul1.s: New. * ld-powerpc/powerpc.exp: Add it.
