Add support for G13 and G14 flag bits in RL78 ELF binaries.
inc * rl78.h (E_FLAG_RL78_G10): Redefine. (E_FLAG_RL78_CPU_MASK, E_FLAG_RL78_ANY_CPU, E_FLAG_RL78_G13 E_FLAG_RL78_G14): New flags. bin * readelf.c (get_machine_flags): Decode RL78's G13 and G14 flags. gas * config/tc-rl78.c (enum options): Add G13 and G14. (md_longopts): Add -mg13 and -mg14. (md_parse_option): Handle -mg13 and -mg14. (md_show_usage): List -mg13 and -mg14. * doc/c-rl78.texi: Add description of -mg13 and -mg14 options. bfd * elf32-rl78.c (rl78_cpu_name): New function. Prints the name of the RL78 core based upon the flags. (rl78_elf_merge_private_bfd_data): Handle merging of G13 and G14 flags. (rl78_elf_print_private_bfd_data): Use rl78_cpu_name. (elf32_rl78_machine): Always return bfd_mach_rl78.
