From 80591e61a0f7e88deaada69844e4a31280c4a38f Mon Sep 17 00:00:00 2001 From: Luc Van Oostenryck Date: Sat, 9 Nov 2019 13:12:16 +0100 Subject: kbuild: tell sparse about the $ARCH Sparse uses the same executable for all archs and uses flags like -m64, -mbig-endian or -D__arm__ for arch-specific parameters. But Sparse also uses value from the host machine used to build Sparse as default value for the target machine. This works, of course, well for native build but can create problems when cross-compiling, like defining both '__i386__' and '__arm__' when cross-compiling for arm on a x86-64 machine. Fix this by explicitely telling sparse the target architecture.
