Hi, so this somehow looks like for a not yet absolutely clear reason to me, when building ghci, we fail to link in libffi, for some configurations.
Joachim, as far as I could see, you are using ghc 8.0.1 to boostrap the compiler. Thomas are you by any chance bootstrapping with 8.0.1 as well? I assume Ben bootstraps wit 8.2.1. I'll set up a Ubuntu 16.10 machine tomorrow and try to reproduce this. Joachim, is perf.haskell.org running Ubuntu as well?
