OSX and Windows are both exempt from this discussion.  Each has its own private copy of an ancient version of libffi: Modules/_ctypes/libffi_osx/ and Modules/_ctypes/libffy_msvc/.

I would be in favor of switching to --with-system-ffi by default for 3.6 and deprecating building with the bundled full copy of libffi (Modules/_ctypes/libffi/), to be removed in 3.7.  OSX would also default to --with-system-ffi, but would still fall back to its private copy when a system copy isn't available.

It seems like most Linux and BSD distributions would be better off with system-ffi.  I'm not sure how cross-builds would have to deal with things in 3.7, but they already have to deal with dependencies like openssl, bz2, and lzma; adding libffi to that mix shouldn't be that big of a deal.

Adding Ned to confirm that building OSX installers wouldn't be affected as long as we don't touch Modules/_ctypes/libffi_osx/ and there's not a system copy of libffi available.
