It appeared with the addition of -no-add-needed, I've downgraded the buildds again, until investigation happens. Apparently what happens is that the object files emit a weak reference to pthread_cancel, issued by some inline macro of g++, in order to be able to cancel a thread when pthread is linked in. libSDL does pull libpthread, but the weak reference doesn't manage to catch the reference.
