Either that (this is how the `cereal` package does it for instance) or
by a pure CABAL solution, which switches between two internal .hs files
based on `impl(ghc >= 7.2)`, or maybe a CABAL-flag-based approach... so
this is just an implementation detail[1] which can be decided once it is
clear, whether adding `genericRnf` is a good idea at all


 [1]: another impleemtation detail would be, whether to make
      `genericRnf` visible directly in `Control.DeepSeq` or in a
      separate module such as `Control.DeepSeq.Generics`
