You could attempt to use a global config.cache with some of common
long running values cached. Run ./configure -C and examine the
resulting config.cache for interesting things to cache (F77?). Then
configure with --cache-file=<file>. This can result in weird failures,
though, if the configure script also plays with these variables. But
you could probably find a pretty minimal set of cached values that
would result in a nice speedup.
