(arm_interwork_jtab): Use bx insn. (thumb_jtab): Likewise. (MARM_INTERWORK): New machine type. (rvaafter): Handle it. (rvabefore) Likewise. (asm_prefix): Likewise. (gen_exp_type): Check machine type instead of interwork flag. (make_one_lib_file): Likewise. (make_head): Likewise. (make_tail): Likewise. (usage): Update machine types.
