Subject: [PATCH] Include directory for OCaml's C headers.

Make an include directory and symlinks ocaml's C header files into
that directory.  By having an include directory it is automatically
propogated as to NIX_CFLAGS_COMPILE for anyone who uses ocaml as a
build input.

(Proposed on the mailing list by Russell O'Connor.)
