kbuild: Inform user to pass ARCH= for make mrproper
When cross-compiling an out-of-tree build with an unclean source tree directory, the build fails with: /path/to/kernel/source/tree is not clean, please run 'make mrproper' in the '/path/to/kernel/source/tree' directory. However, doing so does not fix the problem, as "make mrproper" now requires passing the target architecture to the make command, else it won't remove $(srctree)/arch/$(SRCARCH)/include/generated. "git ls-files -o" doesn't give a clue, as it doesn't list (empty) directories, only files. Improve usability by including the ARCH= option in the error output. Fixes: a788b2ed81ab ("kbuild: check arch/$(SRCARCH)/include/generated before out-of-tree build") Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
