From 621da4ba0e244ba3cfb2e8a9a9055299ec0ab0d3 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Thu, 22 Aug 2019 13:46:09 +0900 Subject: kbuild: Inform user to pass ARCH= for make mrproper only when necessary Since commit 3a475b2166fd ("kbuild: Inform user to pass ARCH= for make mrproper"), if you try out-of-tree build with an unclean source tree, it suggests to run 'make ARCH= mrproper'. This looks odd when you are not cross-compiling the kernel. Show the 'ARCH=' part only when ARCH= was given from the command line. If ARCH is the default (native build) or came from the environment, it should simply suggest 'make mrproper' as before.
