It's easy to parameterize builds in Jenkins based on different values of an environment variable, so Johan and I just have different versions of GHC installed side by side, and then set $GHC_VERSION to "7.6 7.4 7.2 7.0 6.12" (or whatever), put /usr/local/$GHC_VERSION/bin at the front of $PATH, and the right thing happens.
