* Makefile (dist-separate): New variable.
	(glibc-%.tar rule): Make separate tar files for add-ons listed there.
	Depend on their configure files.
	(dist-do-separate-dirs): New canned sequence to do that.
	(dist-separate-libidn, dist-separate-linuxthreads): New variables.
	(dist): Depend on add-on tar files based on $(dist-separate).
	(dist-version): New variable, default to $(version).
	(tag-for-dist, dist): Use that in place of $(version) in deps.
