I understand where you're coming from but I think this is opposite to
the style preferences in musl, which are to avoid dependence on
internal things and directly use portable conditions based on public
interfaces where possible. The existing tests are all completely valid
even outside musl, without depending on any musl-internal stuff. If
the intent is not clear, perhaps some simple comments would suffice?
