IFUNC is fine.  The problem is with x32.  On x32, PLT rewrite generates:

   0xf7fbe060 <+0>:     jmp    0x401030
   0xf7fbe065 <+5>:     int3
   0xf7fbe066 <+6>:     int3
   0xf7fbe067 <+7>:     int3
   0xf7fbe068 <+8>:     int3
   0xf7fbe069 <+9>:     int3
   0xf7fbe06a <+10>:    int3
   0xf7fbe06b <+11>:    int3
   0xf7fbe06c <+12>:    int3
   0xf7fbe06d <+13>:    int3
   0xf7fbe06e <+14>:    int3
   0xf7fbe06f <+15>:    int3

0xf7fbe060 + 0x401030 overflows.
