Comment (by Ben Gamari <ben@…>):

 Revert dynamically linking ghc.

 Building a dynamically linked ghc is broken do to incorrectly building
 and installing libffi. This disables building a dynamically linked ghc
 and ghc-iserv-dyn while keeping most of the code in the relevant
 commits: 79d5427e1 and 89fa34ecd

 Test Plan:
 Ensure build environment does NOT have a system libffi installed (you
 may want to use a nix environment).
 Then `hadrian/build.sh -c --flavour=default`.
