Bug#844323: fixed in ghc 8.0.1-13

[Breno Leitao]

I just tested haskell-zeromq4-haskell build with a patched GHC and it
worked fine, so, I understand also that the problem is fixed.

I just installed the packages also, and they seem to be working properly:

dpkg -l | grep zeromq
ii  libghc-zeromq4-haskell-dev                       0.6.5-5                    
       ppc64el      bindings to ZeroMQ 4.x
ii  libghc-zeromq4-haskell-doc                       0.6.5-5                    
       all          bindings to ZeroMQ 4.x; documentation
ii  libghc-zeromq4-haskell-prof                      0.6.5-5                    
       ppc64el      bindings to ZeroMQ 4.x; profiling libraries


Thanks!
