I understand the problem and I think I know how to fix it, but I have a
question:

Is code like this supposed to be valid?

  extern void * ffoo1c (void);
  void * foo1c (void)
  {
    return (void *)ffoo1c;
  }
  extern void * ffoo1c (void) __attribute__((weak));

If so, why do we have a warning in declare_weak that says:

  "weak declaration must precede definition"

?  This would seem to be exactly that case.

My patch causes us to issue that error, causing some of weak-*.c tests
to fail.

Something is wrong: either the error message or the test.  Which one?
