[RFA] toplev.c tweak

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

I'm trying to keep the initialization code in toplev.c clean;
someone confused it a bit with randomize().  This puts just one
call to randomize() in its correct location.

OK to commit?  Bootstrapped x86 NetBSD C,ObjC,C++ no regressions.

Neil.

	* toplev.c (print_switch_values, toplev_main): Remove calls to
	randomize().
	(process_options): Call randomize here.
