I have just struggled with building CPython with the _ctypes module. Fundamentally, the problem appears to be that configure uses pkgconfig to find the libffi include directory, while setup.py's detect_ctypes only uses the global list of library directories. I have made an attempt at fixing this by having configure produce the directory containing libffi (`LIBFFI_LIBDIR`) and setup.py use this. However I've hardly any experience with autotools, so I would be very happy to be corrected if this is no use at all. The PR is https://github.com/python/cpython/pull/20451
