Why does autogen.sh throw away the config cache?

The following stuff in `autogen.sh' seems wrong to me.

    # toss our old config.cache. it may be invalid now.
    rm -f config.cache

One needs to toss the cache when the results of tests have changed,
not when the tests have changed. I haven't really noticed that that
happens too often.

What was the specific motivation for this?
