* configure.in: Strip --host and --target options from

	CONFIG_ARGUMENTS, and always configure for --host only.  Add
	--with-cross-host option when building with a cross-compiler.
	* configure: Canonicalize the arguments put into config.status by
	always using `=' for an option with an argument.  Pass a presumed
	--host or --target explicitly.
