Ok, so what? Mac OS X is 64-bit now, so are some versions of Windows and Linux, so get used to it. :)

Again, so what? "i386" in "uname -a" is pretty much irrelevant to everything. I'm not even sure that has anything to do with whether the kernel is running 32-bit or 64-bit. Even if it does, that's also irrelevant to whether you can run 64-bit software. You can run 64-bit software with a 32-bit kernel. I'm doing it right now.

Yes, sorry, ffmpeg does not support changing build_arch:
But it should build fine for x86_64. Have you tried that?
