I had the same issue with a machine where libffi-dev is not available.

The first fix is to modify pypy/jit/metainterp/optimizeopt/fficall.py
and move the line "from pypy.rlib.libffi import Func" shortly before
the place where "Func" is used.

Then, I don't remember whether the options "--withoutmod-_ffi
--withoutmod-_rawffi"
were necessary. These modules (i.e ctypes)  won't be available anyway.
