Fix x86_64 installation and update to 1.70.02.

version 1.70.02 (May 22, 2012)

[-] Corrected the optimization of segment prefixes when the extended syntax
    of some string instructions ("cmps", "lods", \ 
"movs" and "outs") is
    used in long mode. Now it is consistent with optimizations done with
    all the other instructions.
