      Description

        I found that not all libraries are linked with -z,noexecstack.
        This lead to errors with our linuxppc64 build. The linker omitted
        the flag altogether, which is interpreted as a lib with execstack.

        This fix contains a small test that scans all libraries in the tested VM
        to have the noexecstack flag set. It utilizes the elf parser in the VM for this.
