Comment # 1 on bug 1202318 from Dirk Weber

To avoid the use of john by the seccheck scripts a workaround would be to
uninstall the package john.
If john is not available the seccheck scripts skip the check for guessable
passwords.

The better solution would be that x86_64 packages run on x86_64 CPUs and do not
require some random CPU features which might be available or not.

Especially as a Phenom II is probably faster than a Celeron with AVX support...
