OK, but as I wrote, config.guess currently only maps some recognized
systems to different names. This case is different because for ppc64le
the output of 'autoconf-config.guess' would be an emtpy string and a
quite big error message on stderr. Do you really want that we make
Linux/ppc64le the default fallback in config.guess if
'autoconf-config.guess' can not detect a system?

Or should we exceptionally just patch 'autoconf-config.guess' if we
know that we will update it anyway with a new version within a few
weeks? I think I'd prefer this solution, because this is just one
change which will be automatically removed once we integrate the new
'autoconf-config.guess' version. If we just hack 'config.guess' we
would have to manually take that change back once we get the new
'autoconf-config.guess' version.

In any case I'd kindly ask you to start the 'legal approval dance' :)

Volker
