This seems wrong for weak aliases. 

I'm not sure. aliases have to be to another symbol defined in the same
translation unit.

Not if they're weak references:

static void f() __attribute ((weakref, alias ("g")));

int main()
{
  if (f)
    f();
}

does not require a definition of g. Apparently weakrefs are different from weak aliases; I was previously confusing the two. But this case still involves attribute "alias".
