From 7b3c70c43c13ad8e59f5561b154663d6bdb77021 Mon Sep 17 00:00:00 2001 From: WANG Xuerui Date: Mon, 31 Jul 2023 18:49:11 +0800 Subject: raid6: test: only check for Altivec if building on powerpc hosts Altivec is only available for powerpc hosts, so only check for its availability when the host is powerpc, to avoid error messages being shown on architectures other than x86, arm or powerpc.
