Would a test on is_bare_repository() suffice for your use-case? That
is, something like this:
if (!add_gitlink_odb(path->buf)) {
linked_odb = 1;
if (resolve_gitlink_ref(path->buf, "HEAD", sha1))
die("Unable to lookup HEAD in %s", path->buf);
} else if (!is_bare_repository())
return 0;
If this isn't good enough, how do you propose it be solved?

This function is local to tree.c, but your point is still valid.
