This is not what I was talking about.  The INT/INTDEF stuff is meant
to be used to call functions defined in libc.so from inside the
libc.so.  This means:

- using macros is really not the scalable.  Defining macros for each
  function will be a nightmare.  We use function pointers occasionally
  which cannot be handled with macros.

- making the mechamism dependent on some symbol related to rtld is wrong
  since the same mechanism must be used in libc.so as well.
