Comment 22 for bug 808829

Added the hardening to the cups-pk-helper package and checked whether system-config-printer still works correctly with it which is the case. Made build system more verbose to check whether hardening options got really applied on compiling and linking, which is also the case.

Checked also the test programs. They do not serve for an automated build by the build server's system user for build processes. The test programs are based on print queues with fixed given names and they also should do their job only without asking for a password in some form if the calling user has appropriate admin privileges. Therefore I did not call them during the build process.
