DESCRIPTION OF INCORRECT BEHAVIOUR:
Failed to build groff on ppc64le machine due to outdated config.guess.

SUGGESTED FIX [optional]:
Update the config.guess to support the ppc64le (IBM powerPC Little Endian).
latest config.guess with ppc64le support is available at http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess;hb=HEAD .
