We don't need to stabilise this _yet_, but it's important that we do it before glibc-2.34 is (eventually) stable, as it contains the various gnulib fixes. I'm filing this now because we're likely to have a lot of packages where we need the right gnulib stuff to trickle down and this is one ticked off the list. Changes were pretty minor and part of the reason for the release was just to sync gnulib. Won't CC arches just yet.
