Hmm... then this is not the use case I had in mind, and some other
factor is at work here. Your use case is supposed to be handled by
this fragment from init_callproc:
if (data_dir == 0)
{
Lisp_Object tem, tem1, srcdir;
Lisp_Object lispdir = Fcar (decode_env_path (0, PATH_DUMPLOADSEARCH, 0));
srcdir = Fexpand_file_name (build_string ("../src/"), lispdir);
tem = Fexpand_file_name (build_string ("NEWS"), Vdata_directory);
tem1 = Ffile_exists_p (tem);
if (!NILP (Fequal (srcdir, Vinvocation_directory)) || NILP (tem1))
{
Lisp_Object newdir;
newdir = Fexpand_file_name (build_string ("../etc/"), lispdir);
tem = Fexpand_file_name (build_string ("NEWS"), newdir);
tem1 = Ffile_exists_p (tem);
if (!NILP (tem1))
Vdata_directory = newdir;
}
}
So somehow the call to Fequal returns nil in your case, when it
shouldn't. Please step with a debugger into this code and see why it
fails to detect that you are invoking Emacs from the source directory.
My crystal ball says some symlinks are involved.

Only for the NS build.

That's the code above, but it somehow isn't working in your case.
