S12Z: New 32 bit Reloc.
Third party tools produce 32 bit relocs at index 6 with strange properties. This change moves the existing 32 bit reloc (R_S12Z_EXT32) to index 7 and introduces a new one (R_S12Z_CW32) at index 6 to try to support code generated by these tools. * bfd/elf32-s12z.c (elf_s12z_howto_table) [R_S12Z_CW32]: New member. * binutils/readelf.c (is_32bit_abs_reloc): Reloc type 7 is also 32 bit. * include/elf/s12z.h (elf_s12z_reloc_tpe) [RELOC_NUMBER (R_S12Z_CW32)]: New enum.
