I am far from a libffi expert -- I've never done a libffi port of any
kind.  But, I didn't want your message to go unanswered.

AIUI to do a port of the closures code, you have to understand the
target's ABI and write some assembly code to handle converting the
incoming arguments into the form libffi exports.  Maybe the simplest
way to go about this is to read and understand one of the other ports.
