Small cleanup of toplev.c

[Neil Booth <neil at daikokuya dot co dot uk>]

A small cleanup of toplev initialization.  OK?

Neil.

	* toplev.c (aux_base_name, filename): Make static.
	(lang_dependent_init): Don't duplicate name.
	(process_options): Set aux_base_name here, not...
	(do_compile): ...here.  Change protoype.
	(toplev_main): Move some code from do_compile.
