Description of problem:
valgrind doesn't work on x86_64

Version-Release number of selected component (if applicable):
valgrind-3.2.3-5

How reproducible:
Every time.

Steps to Reproduce:

valgrind ls

  
Actual results:

==24551== valgrind: Unrecognised instruction at address 0x4015081.
==24551== Your program just tried to execute an instruction that Valgrind
==24551== did not recognise.  There are two possible reasons for this.
==24551== 1. Your program has a bug and erroneously jumped to a non-code
==24551==    location.  If you are running Memcheck and you just saw a
==24551==    warning about a bad jump, it's probably your program's fault.
==24551== 2. The instruction is legitimate but Valgrind doesn't handle it,
==24551==    i.e. it's Valgrind's fault.  If you think this is the case or
==24551==    you are not sure, please let us know and we'll try to fix it.
==24551== Either way, Valgrind will now raise a SIGILL signal which will
==24551== probably kill your program.
