tools/ocaml: ask compiler for correct library

OCaml libraries will live in /usr/local/ if the user compiles OCaml
from source. This patch asks the OCaml compiler where we should look
for libraries.

NB: it may be that we should do the same thing for the NetBSD case,
but I don't have a BSD box to test this out.
