Yes. Any program built with upstream binutils has extra R_PARISC_NONE
relocs. 

If built with the upstream bintuils:

Relocation section '.rela.dyn' at offset 0x32c contains 5 entries:
 Offset     Info    Type            Sym.Value  Sym. Name + Addend
00000000  00000000 R_PARISC_NONE                                00000000

Symbol table '.dynsym' contains 12 entries:

If built with debian binutils:

Will complain on a bad binutils.
