Drop Support for GHC 7.2.2?
The last working CI Job on Travis suggests that hpc is no longer buildable with GHC 7.2.2. https://travis-ci.org/github/ghc/packages-hpc
If support for GHC versions < 7.4 is dropped, all the remaining CPP in hpc is superfluous and could be removed. Alternatively, hpc needs to be fixed to work again with 7.2.2
