* Makefile.tpl: Rearrange by moving recursive_targets rules

	into their proper sections.
	* Makefile.tpl (top level bootstrap support): Move disabling
	of coverage flags from 'make' to 'configure'; improve comments.
	* Makefile.in: Regenerate.

	* Makefile.tpl (experimental top level bootstrap) Move stage1
	language setting from all- target to configure- target; disable
	intermodule optimization in stage 1; prevent gratuitous rebuilds
	of stage 1.
	* Makefile.in: Regenerate.
	* configure.in: Comma-separate stage 1 language list for top
	level bootstrap.
	* configure: Regenerate.

	* Makefile.tpl: Clean up experimental top level bootstrap support:
	note known problems; set CONFIG_SHELL; don't set BUILD_CC; relocate
	prev-gcc in configure- targets as well as all- targets.
	* Makefile.in: Regenerate.
