Comment (by afarmer):

 Alright, I built 7.10.2+LHS patch+this patch and then used that to build
 stackage (LTS 3.8) as a smoke test. Every package built and tested (for
 whatever testing stackage-curator does) successfully.

 I'll see if I can run benchmark suite on something like text/aeson as a
 further smoke test, but hopefully this is good to go.
