Just set the config.cache variable to the wrong result and you'll have
such a system :-)

I don't think we should introduce a patch with functionality that is
known-not-good and likely to change. Let's at least try to get it to
what we've now agreed to be the good, even if it takes a few minutes
longer.
If you want an actual example, try binutils and gcc from CVS for
arm-linux-gnu. GCC says it needs binutils 2.17, but 2.16.9* already
have it, so configure gets it wrong.
Also, please check in AC_ARG_ENABLE that $enable_tls expands to either
yes or no, and error out (or at least print a warning) otherwise.
