I'm afraid I don't understand the principle of your test, as it seems
to me that it should succeed in every case (it'll just link against a
static libb instead of a dynamic one).

I've changed the test to instead try to determine if it was able to
create a dynamic libb or not. It does this by looking at the
library_names field in libb.la.

I've confirmed that this test catches the bug here.
