If you look at the libffi reference patch I have included, the architecture specific changes to use trampfd just involve a single C function call to a common code function.
No idea what libffi is, but it must surely be simpler to rewrite it to avoid nested function definitions. Or find a book from the 1960s on how to do recursive calls and nested functions in FORTRAN-IV.
