Yes; /usr/share/doc/autotools-dev/README.Debian.gz has lots of advice on
this.

I suspect the extended description has been improved since then.

It's hard to tell entirely programmatically whether a package updates
config.guess/config.sub during build - there are several ways to do so,
and a number of possible layouts - which is why it's timestamp-based and
we bump the timestamp for new ports.  The check is actually fairly
sophisticated if you read its code, though.
