config.sub/config.guess are part of the gnu "config" project:
http://savannah.gnu.org/git/?group=config

automake releases usually incorporate the version which is current at 
the time of a new automake release.

Autoconf-2.69  - This is entirely unrelated config.sub/guess.

I don't know when it was added, but automake-1.13 has it.

My recommendation: Instead of mucking around with 
automake/autoreconf-1.13+ and its incompatiblities, get the current 
version of config.guess/config.sub from the config project and add them 
as a patch to your package.
