An other tool which seem to have a stable output is 
/usr/sbin/getenforce, it outputs either Disabled, Permissive or 
Enforcing. But again this is a tool that is part of SELinux toolset 
(selinux-utils package).

Like I said in my previous mail:

This is basically what getenfoce utility (and libselinux) is doing
