[PATCH] gnu: Add ECL.

[Taylan Ulrich Bayırlı/Kammer]

The license declaration of this recipe is noteworthy.  I diligently
commented about the places each license appears in, from the non-LGPL2
places mentioned in the "Copyright" file, so as to make it easier to
verify nothing has been left out.  Tell me if I overdid it; I couldn't
see a better way to keep some sanity amid the license jungle.
