Subject: 	* elf64-s390.c (elf_s390_check_relocs): Set DF_TEXTREL if the 
 reloc is against read-only section. 	(elf_s390_size_dynamic_sections): Use
 DF_TEXTREL flag instead of 	looking up section names for DT_TEXTREL. 
 (elf_s390_reloc_type_class): New. 	(elf_backend_reloc_type_class):
 Define.

	* elf32-s390.c (elf_s390_check_relocs): Set DF_TEXTREL if the
	reloc is against read-only section.
	(elf_s390_size_dynamic_sections): Use DF_TEXTREL flag instead of
	looking up section names for DT_TEXTREL.
	(elf_s390_reloc_type_class): New.
	(elf_backend_reloc_type_class): Define.

	* elf32-ppc.c (ppc_elf_check_relocs): Set DF_TEXTREL if the reloc
	is against read-only section.
	(ppc_elf_size_dynamic_sections): Use DF_TEXTREL flag instead of
	looking up section names for DT_TEXTREL.
	(ppc_elf_reloc_type_class): New.
	(elf_backend_reloc_type_class): Define.
