While we do actually want _GNU_SOURCE to be defined for users of kselftest_harness we haven't actually done that yet and this is causing widespread build breaks which were previously warnings about uses of asprintf() without prototypes, including causing other test programs in the same directory to fail to build. Since the build failures that are introduced cause additional issues due to make stopping builds early replace the static_assert() with a missing without making the error more severe than it already was. This will be moot once the issue is fixed properly but reduces the disruption while that happens.
