    rtld - Fix ifunc relocations
    
    * ifunc relocations had a bug that caused an immediate seg-fault.
      Apparently this type of relocation is not used very much, we've
      never encountered it before.  But the qemu port uses it.
    
    * Fix the bug.  Basically missing lockstate and the top level in
      rtld was expected to hold the bind lock.
