This adds support for marking RL78 binaries as either supporting 32-bit
or 64-bit doubles. It also makes the linker complain if the user attempts
to link together binaries with different sized doubles.
* elf32-rl78.c (rl78_elf_merge_private_bfd_data): Complain if
64-bit doubles objects mix with 32-bit doubles objects.
(rl78_elf_print_private_bfd_data): Describe 64-bit doubles flag.
* readelf.c (get_machine_flags): Handle RL78 64-bit doubles flag.
* config/tc-rl78.c (enum options): Add OPTION_32BIT_DOUBLES
and OPTION_64BIT_DOUBLES.
(md_longopts): Add -m32bit-doubles and -m64bit-doubles.
(md_parse_option): Parse -m32bit-doubles and -m64bit-doubles.
(md_show_usage): Show all of the RL78 options.
(rl78_float_cons): New static functions.
(md_pseudo_table): Update handler for "double".
