I'm not sure it's exactly what you have in mind, but there is
something rather like this on the roadmap:
As you say, the new approach will provide better support for cross compilation.

That's the usual situation, but it's occasionally useful to bind
static elements (struct & union definitions, compile-time constants,
etc.) only, in which case it's preferable to pull all the
layout/constant information into the generated OCaml code, and avoid
the need to link in C. For example, the Profuse library, which
implements the FUSE protocol, does exactly that:
