re PR other/17361 (gcc driver complains about C++ options when assembling)

	PR other/17361
	* c-opts.c (permit_fortran_options): Delete/obsolete global variable.
	(c_common_init_options): Remove #ifdef CL_F77 code.  Scan command
	line options for "-lang-asm" and if found allow any of the C-family
	front-end options.
	(c_common_handle_option): Remove last use of permit_fortran_options.
