	* gcc.c (lang_specific_pre_link):  New LANG_SPECIFIC_DRIVER function.
	(lang_specific_extra_outfiles):  New LANG_SPECIFIC_DRIVER variable.
	(do_spec, input_filename, input_filename_length):  Make public.
	(main):  Adjust outfiles allocation by lang_specific_extra_outfiles.
	Call lang_specific_pre_link befor elinking.
