It is safer for me in general to never use --build, only --host. config.guess is always doing its job right [1]; if I used --build, I would only increase the risk of mistakes. > Does the error disappear if you also pass the '--build' option to configure? The Autoconf manual says "this will be fixed in the future"; therefore the Automake test suite should be prepared to work with just --host and no --build option.
