Hmmmmmm..... This touches upon an architectural shortcoming in configure. (Some of) the toolchain checks are done after library checks and system checks. They really shouldn't. All checks should be performed with the final toolchain that will later be used during the actual compilation procedure. So this seems like a bandaid necessary due to the architectural problem. Maybe it's time to tackle the underlying problem instead. I've been meaning to for a long time.
