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.
