A quick fix for broken 'make distcheck'
A quick fix for broken 'make distcheck'

The offending target 'test/hs/offline-test.sh' requires the dependencies
even when the test isn't actually run. This is because currently our
Makefile doesn't distinguish between prerequisites for building test
scripts and running them.

This is a quick fix that hides the dependencies if the Haskell tests
aren't built, but it doesn't address the core problem. This will be
fixed in a separate patch series.
