* elflink.h (elf_link_sort_cmp1): Sort RELATIVE relocs first, not
last.
(elf_link_sort_relocs): Adjust accordingly.
* elf64-alpha.c (struct alpha_elf_link_hash_entry): Add reltext flag.
(elf64_alpha_check_relocs): Set it if section this reloc is against
is read-only. Set DF_TEXTREL if a RELATIVE reloc is needed against
read-only section.
(elf64_alpha_calc_dynrel_sizes): Set DF_TEXTREL flag if relocation
is is against read-only section.
(elf64_alpha_size_dynamic_sections): Use DF_TEXTREL flag, don't
check section names.
(elf64_alpha_reloc_type_class): New.
(elf_backend_reloc_type_class): Define.
