From c992c4d80f51540699f33fed067caf6b7c38df79 Mon Sep 17 00:00:00 2001

Subject: Add GNU Guile as an optional embedded scripting language for make.

On configure-enabled systems, configure will detect Guile installed
(using pkg-config, which is how GNU Guile is distributed) and enable
it if so.

On all non-configure-enabled systems, currently, the default is for
Guile support to be disabled.
