So far as I can tell from a quick troll of the git history, we have never
ever updated config.guess/config.sub in released branches. I'm a bit
hesitant to do it in this case either: it would amount to retroactively
adding support for a platform, which sure sounds like a new feature.
My vote would be to adjust your buildfarm critter to only try to build
9.4 and up.
