* elf-bfd.h (struct bfd_elf_special_section): Remove "suffix". Change
type of prefix_length and suffix_length to int. Rename "attributes" to "attr". Comment. (_bfd_elf_get_sec_type_attr): Update prototype. * elf.c (get_special_section): Rewrite. (_bfd_elf_get_sec_type_attr): Return struct rather than passing in attr and type pointers. (_bfd_elf_new_section_hook): Adjust for above. (special_sections): Merge suffix with prefix. Set prefix_length for all entries. Set suffix_length appropriately. * elf32-m32r.c (m32r_elf_special_sections): Likewise. * elf32-m68hc11.c (elf32_m68hc11_special_sections): Likewise. * elf32-m68hc12.c (elf32_m68hc12_special_sections): Likewise. * elf32-mcore.c (mcore_elf_special_sections): Likewise. * elf32-sh64.c (sh64_elf_special_sections): Likewise. * elf32-v850.c (v850_elf_special_sections): Likewise. * elf32-xtensa.c (elf_xtensa_special_sections): Likewise. * elf64-alpha.c (elf64_alpha_special_sections): Likewise. * elf64-hppa.c (elf64_hppa_special_sections): Likewise. * elf64-ppc.c (ppc64_elf_special_sections): Likewise. * elf64-sh64.c (sh64_elf64_special_sections): Likewise. * elfxx-ia64.c (elfNN_ia64_special_sections): Likewise. * elfxx-mips.c (_bfd_mips_elf_special_sections): Likewise. * elf32-ppc.c (ppc_elf_special_sections): Likewise. Fix .plt flags.
