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: a788b2ed81abeb94 ("kbuild: check arch/$(SRCARCH)/include/generated
before out-of-tree build")
