This sounds like a nice idea in concept, but unfortunately the
config.cache files are not meant to be shared between different
packages.  This has been tried before, and it inevitably leads
to disaster.  Most obvious is the possibility of namespace
collision (two packages could use the same variable name for
totally different things) but more subtle issues can come up
too.

Cache values are often interdependent. The success of one depended on another, or on a particular shell variable value when the associated test was run. The linker and preprocessor search paths are a good example of a dependency.
