However, these copied source files were not removed during 'make clean', leaving temporary files in the build directory. Add the clean-files variable to ensure that these copied .c and .S files are properly cleaned up. The notdir() function is used to strip the path prefix, as clean-files expects relative file names without directory components. This ensures the build directory is left in a clean state after make clean.
