(s390_elf_suffix): Add suffix strings for gotoff, gotplt and pltoff. (s390_elf_cons): Map new lenght/elf suffix combinations for gotoff, gotplt and pltoff to bfd relocations. (md_gather_operands): Map new instruction operand/elf suffix combinations to bfd relocations. (tc_s390_fix_adjustable): Add new gotoff, gotplt and pltoff relocations to the list of unadjustable relocations. (tc_s390_force_relocation): Always emit relocations for gotoff, gotplt and pltoff relocations.
