This options allows to easily extend a shell with an OCAMLPATH suitable
for building F* OCaml programs, and also to simply run a build command easily
by prepending fstar.exe --ocamlenv to it.
Example below.
module Hello
open FStar.IO
let _ = print_string "Hello F*!\n"
$ fstar.exe --ocamlenv ocamlfind ocamlopt -linkpkg -package fstar.lib Hello.ml

Hello F*!
Obviously the command required is not as simple as it could be, but this
is already an improvement since it provides a standard way of locating
the needed OCAMLPATHs.
