This is just a test harness. ~Andrew

Use of Xeon Phi features was dropped earlier on; this one was overlooked. Fixes: 85191cf32180 ("x86: drop Xeon Phi support") Signed-off-by: Jan Beulich <jbeulich@suse.com> --- In principle it looks as if we could now drop all of this checking, as gcc5 supports all of the features we check for. AVX512-4FMAPS is an example though where checking helps, as this and other Xeon Phi features were supported by an intermediate range of gcc versions.
