# On FreeBSD, GMP's `config.guess' detects the sub-architecture (e.g.,
# "k8") and generates code specific to that sub-architecture, in spite of
# `--enable-fat', leading to illegal instructions and similar errors on
# machines with a different sub-architecture.
# See <http://hydra.nixos.org/build/2269915/nixlog/1/raw>, for an example.
# Thus, use GNU's standard `config.guess' so that it assumes the generic
# architecture (e.g., "x86_64").
