	* readelf.c (get_machine_flags): Handle RL78 G10 flag.

	* config/tc-rl78.c (elf_flags): New variable.
	(enum options): Add OPTION_G10.
	(md_longopts): Add mg10.
	(md_parse_option): Parse -mg10.
	(rl78_elf_final_processing): New function.
	* config/tc-rl78.c (tc_final_processing): Define.
	* doc/c-rl78.texi: Document -mg10 option.

	* rl78.c (E_FLAG_RL78_G10): Define.

	* lib/ld-lib.exp (check_shared_lib_support): Note that the RL78
	does not support shared library generation.
