* elf64-ppc.c (ppc64_elf_check_relocs): Don't call
create_linkage_sections here..
(ppc64_elf_init_stub_bfd): ..do so here. Return status.
(create_linkage_sections): Move earlier in file.
(ppc64_elf_setup_section_lists): Remove now useless htab->brlt test.
* elf64-ppc.h (ppc64_elf_init_stub_bfd): Update proto.

Check return from ppc64_elf_init_stub_bfd.
