Before kernel 4.11 CONFIG_DEBUG_RODATA depended on CONFIG_KERNEL_DEBUG being set, and the 4.4 linux-kvm kernel does not set this option (I assume in the name of performance). I'm therefore fixing up the qrt testcase to not fail in this situation, but only for pre-4.11 kernels. For kernels based on 4.11 and later, where the CONFIG_STRICT_KERNEL_RWX option does not depend on CONFIG_KERNEL_DEBUG being set, the Ubuntu Security Team would like to see CONFIG_STRICT_KERNEL_RWX enabled.

QRT commit https://git.launchpad.net/qa-regression-testing/commit/?id=d7e8c14e20ad00a2bb089c46b28b5f4c0c265849 puts this into place.

Thanks.
