This is the ia64 define:

#define DL_DT_INIT_ADDRESS(map, addr) DL_AUTO_FUNCTION_ADDRESS (map, addr)

Calls to init on ia64 always use a function descriptor.

While it's possible that DT_INIT and DT_FINI shouldn't point at function
descriptors, the above hack can't be right since DL_DT_INIT_ADDRESS is used
for calling init() from dl-init.c:

      init_t init = (init_t) DL_DT_INIT_ADDRESS
	(l, l->l_addr + l->l_info[DT_INIT]->d_un.d_ptr);

      /* Call the function.  */
      init (argc, argv, env);
