IIUC it's because the expectation is that it's not run very often and
that current machines are fast enough to make it bearable, the advantage
being that when you "aptitude upgrade" you won't waste your time
wondering why configure does not notice that your libjpeg62 doesn't
exist any more and how to coerce configure into doing its job
(i.e. find out that you need to remove the config.cache that you'd
never heard of).
I.e. the problem of autoconf's cache is that there's no automatic way to
discover when it's stale.
