	(finishing slow-motion replay)
	* configure: Remove skip-this-dir support.
	* Makefile.tpl: Remove skip-this-dir support.

	* Makefile.tpl: Remove leftover support for non-autoconfiscated
	subdirectories.
	* Makefile.in: Regenerate.

	* Makefile.tpl: Strip out useless setting of 'dir'.
	* Makefile.in: Regenerate.

	(finishing slow-motion replay)
	* configure.in: Fix deeply stupid bug.

	* configure.in: Introduce RAW_CXX_FOR_TARGET and simplify embedded
	shell code in CXX_FOR_TARGET
	* Makefile.def: Introduce raw_cxx.
	* Makefile.tpl: Use raw_cxx to select between CXX_FOR_TARGET and
	RAW_CXX_FOR_TARGET.

	(finishing slow-motion replay)
	* Makefile.tpl: Remove unnecessary ifs.
	* Makefile.in: Regenerate.

	* Makefile.tpl: Implement soft dependency machinery.  Maybe-ize
	dependencies.  Maybe-ize build-libiberty.  Create dummy install
	targets for 'no_install' modules.
	* configure: Move GDB_TK substitution to configure.in.  Move
	build_modules stuff to configure.in.
	* configure.in: Implement soft dependency machinery.  Maybe-ize
	GDB_TK, rearrange slightly.  Move build_modules stuff from configure.
