You're right, it doesn't link against libffi, I only assumed this,
because utils/ghc-pwd/ghc-pwd was (really unnecessarily?) linked asked
libffi, so that I wasn't able to install the whole.

Sorry for the confusion. The question remains, why is
utils/ghc-pwd/ghc-pwd linked against libffi in the official binary-dist?
