When clang's -Qunused-arguments is dropped from KBUILD_CPPFLAGS, it points out that there is a linking phase flag added to CFLAGS, which will only be used for compiling clang-16: error: argument unused during compilation: '-shared' [-Werror,-Wunused-command-line-argument] '-shared' is already present in ldflags-y so it can just be dropped.
