Currently we use weak undefined symbol, foo, to do if (&foo != 0) foo is defined. else foo isn't defined. We want is to define foo as a secondary symbol so that we can always use foo without checking. If there is a primary one in a .o file and .so file, we will get the primary one, otherwise, we will use the secondary one. -- H.J.
