+Subject: [PATCH] util/format: Check for NEON before using it
+
+This fixes build on rpi0-w and any other machine which does not have
+neon unit and is not used as FPU unit
+
+Fixes errors e.g.
+
+In file included from ../mesa-21.3.0/src/util/format/u_format_unpack_neon.c:35:
+/mnt/b/yoe/master/build/tmp/work/arm1176jzfshf-vfp-yoe-linux-gnueabi/mesa/2_21.3.0-r0/recipe-sysroot-native/usr/lib/clang/13.0.1/include/arm_neon.h:32:2: error: "NEON support not enabled"
