 Compiling git HEAD (e02ef0e6d4eefa5f0) on AArch64 hardware using ghc-7.6.3
 from Debian as the bootstrap compiler. LLVM is version 3.6.

 It fails with:

 It seems that `inplace/lib/bin/ghc-stage1` (which is working fine) is
 statically linked to all the Haskell libraries where as `inplace/lib/bin
 /ghc-stage2` is dynamically linked which would explain why stage1 works
 fine and stage2 segfaults.
