Extend unit test for GHC options as part of release process?

At 976f86ab67952d377c25f19e6a2594e0000900a2, I'm getting `-Wunused-top-binds` when building `cabal.project`:

```
$ cabal build all --enable-tests --enable-benchmarks

There's a note about how to collect newer GHC options but could we automate this with a script and also add the task of updating this unit test as part of the cabal release process?
