It turns out that neither libffi nor ffcall are a useful part of such
a solution: libcc.fs uses neither. What it does is to generate a
wrapper function (that accesses the Forth stacks) for every C function
we want to call, then compile these functions using the C compiler
(which knows about the types and macros and stuff), and then
dynamically link them; the wrapper functions all have the same
prototype, so they can be called through an indirect function call, no
libffi needed.
For the limited problem of calling JNI functions libffi is apparently
useful, but JNI cannot call arbitrary C functions.
