Thanks, this patch version does that.

2012-02-24  Joseph Myers  <joseph@codesourcery.com>

	* manual/Makefile (libc-texi-generated): New variable.  Include
	version.texi.
	(libc.dvi, libc.pdf, libc.info, libc/index.html): Depend on
	$(libc-texi-generated), not duplicated list of files.
	(version.texi, stamp-version): New rules.
	(realclean): Remove $(libc-texi-generated), not individual files
	from that list.  Do not remove dir-add.texinfo.
	* manual/libc.texinfo: Comment out uses of edition numbers and
	references to printed manual.  Remove last-updated dates.
	(EDITION): Comment out.
	(ISBN): Likewise.
	(VERSION, UPDATED): Remove.
	(version.texi): Include.
