I still prefer the idea of being able to set an environment variable,
$CONFIG_GUESS, rather than going hunting ourselves.  Then, porting to a
new config.guess script is a matter of calling:

./configure CONFIG_GUESS=/path/to/new/version

rather than hoping that a hard-coded hunt will find the new config.guess
appropriate for the system wanting the upgrade path.
