TIL - thank you! i've never seen this mentioned before. (Perhaps
because i only use autoconf as an end-user, rather than as a dev.)
I used it on OpenBSD in the 90s to make ports builds go much faster in the days before pkgsrc was a going concern. It made a huge difference on my arc machine that was about P75 speed, the speed of a pentium clocked at 75MHz.... it was an R4000PC running at 100MHz iirc.

Looking at section 15.8 of that manual, it looks like i could
specify that `-C` / `--config-cache` be passed to configure by
default site-wide. So i might do so on my Gentoo system - given
most things on that system are locally compiled, it might be an
interesting stress-test data-point regarding configuration
caching.
