When clang's -Qunused-arguments is dropped from KBUILD_CPPFLAGS, it warns while building objects in the purgatory folder: clang-16: error: argument unused during compilation: '-MD' [-Werror,-Wunused-command-line-argument] '-MMD' is always passed to the preprocessor via c_flags, even when KBUILD_CFLAGS is overridden in a folder, so clang complains the addition of '-MD' will be unused. Remove '-MD' to clear up this warning, as it is unnecessary with '-MMD'. Additionally, '-c' is also unnecessary, remove it while in the area.
