Description of problem:
Illegal instruction when using openssl (originally triggered in scipy test suite in bug #1181559)

Version-Release number of selected component (if applicable):
$ rpm -qf /lib/

How reproducible:
Always. Run openssl in gdb

Steps to Reproduce:
1. $ gdb openssl

The instruction is used for detection of CPU features.

Just use 'handle SIGILL nostop noprint' in gdb.
