Ocamlbuild seems to create a symbolic link into the _build directory
when you build a single target.  But it removes that symlink if you
build a different target, and it doesn't produce any symlinks if you
build a *.otarget.

Is there any rationale for this?  It makes it difficult to use the
resulting symlinks in any kind of build script.
