runtime_loader: accept type STT_FUNC when STT_OBJECT is requested

Browse Source 
trying to load a PIE executable produced by golang show the following (for pthread_create)
    12: 0000000000000000     0 OBJECT  GLOBAL DEFAULT  UND pthread_create
 12655: 0000000000000000     0 NOTYPE  GLOBAL DEFAULT  UND pthread_create

It's the same for Linux or Solaris, so I suppose we're being too picky.
