Comment (by neuwirthe):

 I forgot to mention: I also get warnings of the following type:


 [ 1 of 89] Compiling Distribution.PackageDescription.Utils (
 libraries/Cabal/Cabal/Distribution/PackageDescription/Utils.hs,
 bootstrapping/Distribution/PackageDescription/Utils.o )
 You are using a new version of LLVM that hasn't been tested yet!
 We will try though...

 And this is the information abut the version of LLVM I am using:
 pi at raspberrypi32:~/devel/ghc-7.8.4$ /usr/lib/llvm-3.4/bin/opt --version
 LLVM (http://llvm.org/):
   LLVM version 3.4.2

   Optimized build.
   Built Nov  5 2014 (21:06:13).
   Default target: arm-unknown-linux-gnueabihf
   Host CPU: (unknown)
