Turns out there are thirteen!

I’ve attached the patch.  The name of the keyword is not great, so
suggestions there are welcome.  I managed to build all of our Haskell
packages (except for some usual suspects that fail for other reasons).
It’s not so bad, but it’s a bit of a hack.

I’m now wondering why Guix’s treatment of “LIBRARY_PATH” is not just
solving this outright without the need for those flags.  Before I
consider pushing the patch, I’m going to answer that question.  Ideally,
Guix could do more of what it’s good at: understanding the complete
package graph.  :)
