Another thing you can check if is whether the auxv
structures are aligned correctly. In stage1 fix_auxv
if delta % sizeof(*auxv) != 0  you are going to have
problems in the current fixup. You need to do some
extra work for that. 

   if( delta % sizeof(*auxv) != 0 )
   {
      fprintf(stderr, "Fix auxv better....\n");
      struct ume_auxv* temp_auxv = auxv;
      while( temp_auxv->a_type != AT_NULL )
temp_auxv++;
      memmove( (char*)auxv - delta % sizeof(*auxv) ,
auxv,  (temp_auxv + 1 - auxv) * sizeof(*auxv) );
      auxv = (char*)auxv - delta % sizeof(*auxv);
   }

   auxv -= delta/sizeof(*auxv);
