(thumb-*-elf): Handle.
        * configure:  Regenerate.
        * read.c (stringer): Fix typo in comment.
        * write.c (fixup_segment): Don't add symbol value to addend if
        TC_ARM and OBJ_ELF.
        * config/tc-arm.c (md_section_align):  Don't align dwarf debug
        sections.
        (tc_gen_reloc):  Always set the reloc addend to fixp->fx_offset
        for OBJ_ELF.
