	* configure.in (CC_FOR_TARGET, CXX_FOR_TARGET, GCJ_FOR_TARGET,
	GCC_FOR_TARGET, RAW_CXX_FOR_TARGET, GFORTRAN_FOR_TARGET): Find
	them with NCN_STRICT_CHECK_TARGET_TOOL, like the other target
	tools; remove code to manually set them.
	(Target tools): Look in the environment for them.
	* Makefile.tpl (CC_FOR_TARGET, CXX_FOR_TARGET, GCJ_FOR_TARGET,
	GCC_FOR_TARGET, RAW_CXX_FOR_TARGET, GFORTRAN_FOR_TARGET): Redefine.
	(AS_FOR_TARGET, LD_FOR_TARGET, NM_FOR_TARGET): Look into gcc
	build directory.
	(CONFIGURED_CC_FOR_TARGET, CONFIGURED_CXX_FOR_TARGET,
	CONFIGURED_GCJ_FOR_TARGET, CONFIGURED_GCC_FOR_TARGET,

	USUAL_CXX_FOR_TARGET, USUAL_GCJ_FOR_TARGET, USUAL_GCC_FOR_TARGET,
	USUAL_RAW_CXX_FOR_TARGET, USUAL_GFORTRAN_FOR_TARGET): New.
	(CXX_FOR_TARGET_FOR_RECURSIVE_MAKE,
	RAW_CXX_FOR_TARGET_FOR_RECURSIVE_MAKE, RECURSE_FLAGS): Delete.
	* configure: Regenerate.
	* Makefile.in: Regenerate.
