re PR other/3968 (COLLECT_GCC_OPTIONS empty)

	* gcc.c (set_collect_gcc_options): New function, split out from
	main.
	Ignore elided switches.
	(do_spec): Invoke before executing command.
	(do_spec_1): Likewise.
	Fixes PR other/3968.

	* gcc.c (set_input): Export.
	Move declaration ...
	gcc.h (set_input): ... here.

	java:
	* jvspec.c (jvgenmain_spec): Cannot use %umain, breaks
	ASM_FINAL_SPEC.
	(lang_specific_pre_link): Use set_input to set input_filename.
	Append `main' here.
	* jvgenmain.c (usage): Append literal `main' to CLASSNAME.
	(main): Fix definition.
	Strip `main' from classname.
	Fixes PR java/227.
