You can obtain the newest version of config.guess and config.sub from the ‘config’ project at https://savannah.gnu.org/. The commands to fetch them are
$ wget -O config.guess 'https://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess;hb=HEAD' $ wget -O config.sub 'https://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD'

All you need to do, other than moving the files, is to add the following line to your configure.ac.
