Other distributors do the config.guess/sub dance by default IIRC.

A long time ago I implemented the config.guess/sub dance in
config.guess/sub but that was rejected by the upstream config (aka
autotools-dev) maintainer. Then I implemented the config.guess/sub
dance in autoconf but that was rejected by the upstream autoconf
people. Patches attached in case you want to try convincing them
again. Links to the newer threads below, the GNU folks seem to have
lost archives before 2012 on the config-patches list, the first patch
was in 2009 but was only discussed off-list:

Subject: [PATCH] Check a number of paths for newer config.guess/config.sub,
run the latest.
This helps people who are bootstrapping new systems from existing software
that uses GNU autotools, config.guess and config.sub.
This is very useful for distributions like Debian that add new architectures
and then have to update config.sub and config.guess in every single package
that uses automake or have to workaround the problem by adding code to each
package to copy in the latest versions of these scripts from another package
containing the latest version of the scripts (autotools-dev in Debian).
Allow software authors and distro porters to override the latest version.
