Hi Marcus,

   Thanks for bringing this to my attention.  There are three paths
forward, as a I see it:

1. Revert the changes completely, and reintroduce all generated
   configury to the repo.

2. Make no changes, and just ask that developers who care use
   pre-releases of the configury tools (like I was doing with libtool
   for similar reasons).  This is what I would do for the release, so
   aarch64 support would be preserved in the release.

3. Don't revert the changes, but modify the autogen.sh script to pull in
   the newer config.guess and config.sub after the fact.

  Do you see any other solution?  I'd prefer not to go with [1].  How do
you feel about [2] or [3]?

AG
