(* Build a functorized version of the protocol with the
`tezos-protocol-compiler` This is bit hackish...
AFAIK the current version of jbuilder (1.0+beta16) does not allow
to compile with a custom `rule` the `(modules)` of a library.
A trick is to provide the `.cmx` through the `(library_flags)` and
to generate a empty `.ml` to correctly handle the dependencies... *)
