FFI_DEBUG

This seems to mostly be for internal libffi debugging purposes, so not that useful.

FFI_NO_RAW_API

I decided not to bind the raw API as it's undocumented and (AFAICT) never really used in the wild. So this option doesn't matter.

FFI_NO_STRUCTS

No idea why anyone would want this. It doesn't even significantly reduce code size.

FFI_MMAP_EXEC_EMUTRAMP_PAX

This seems useful for Gentoo/PaX. Should be added, but off by default.
