 Whilst this is a nice idea, I'm not sure if it's practical.  My
 reading of the autoconf manual seems to indicate that after the
 standard cache values which autoconf provides, developers are free to
 use whatever cache values they like, which may well conflict.
 Granted, this is probably not going to happen too often, but with a
 collection of software the size of the ports, you have to be careful.
