So it turns out that Eigen's source code comes with some functions that
are officially unsupported by the developers but still available for
use. Guix just doesn't install them. I've attached a patch that *should*
properly install the unsupported files to Eigen's include path.

Also, thanks for helping with this shogun patch!
