	* configure.frag: Delete file.
	* configure.in: Rename the substitution variables
	dep_host_xmake_file and dep_tmake_file to xmake_file and
	tmake_file respectively.  Do not expand $srcdir in the
	value of these; leave that for Make.  Introduce a new
	substitution varaible, all_lang_makefrags, which lists
	subdirectory Make-lang.in files; exclude these from
	all_lang_makefiles, which is now only for subdirectory
	outputs.  Do not invoke configure.frag.  Do not set nor
	AC_SUBST_FILE target_overrides, host_overrides, or
	language_fragments. Create build subdirectories in
	config.status extra commands.
	* configure: Regenerate.
	* Makefile.in: Update substitutions to match changes to
	configure.  Use include directives instead of @-insertions
	to read in host, target, and language fragments.
	(Makefile rule): Do not invoke configure.frag.  Do not copy
	config.status to config.run before executing it.  Set
	CONFIG_HEADERS and CONFIG_FILES so that only Makefile gets
	regenerated.
	(cstamp-h rule): Set CONFIG_FILES as well as CONFIG_HEADERS.

	* Makefile.in: Update substitutions to match changes to
