Used `replace` instead of `add` on the interfaces Hash table (which is
being used as a set), to avoid duplicate entries. The duplicate entries
lead to enormous `caml_globals_map` values.

Also use `replace` instead of `add` on another hash table usage, not
because it was causing any problems but because it seems like `add`
should be avoided outside unusual situations.

Use the same options as in the upstream Makefiles, based on ocaml/Makefile.config
This fixes the missing -ffunction-sections in compilation of C stubs.
We should disable dune behavior of taking C compiler options from
"ocamlc -config" when we move to dune 2.8.

Refactor all .sexp targets into flags.sexp.
