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=<ARCH> mrproper'. This looks odd when you are not cross-compiling the kernel. Show the 'ARCH=<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. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
