Subject: Allow to pass separate configure arguments for build, host and
 target.

/:
	PR bootstrap/45326
	PR bootstrap/45174
	* configure.ac: Honor initial values of $build_configargs,
	$host_configargs, $target_configargs.  Mark the precious, so
	environment settings get recorded.
	* configure: Regenerate.
