問題如下：

$ ARCH=arm64 CC=clang CLANG_TRIPLE=aarch64-linux-gnu- CROSS_COMPILE=aarch64-linux-gnu- CROSS_COMPILE_ARM32=arm-linux-gnueabihf- make all
    scripts/kconfig/conf  --silentoldconfig Kconfig
      CHK     include/config/kernel.release
    Cannot use CONFIG_LTO_CLANG: requires clang 5.0 or later
    make: *** [Makefile:1207: prepare-compiler-check] Error 1

解法如下(clang參數由後置帶入make即可)：

$ ARCH=arm64 make CC=clang CLANG_TRIPLE=aarch64-linux-gnu- CROSS_COMPILE=aarch64-linux-gnu- CROSS_COMPILE_ARM32=arm-linux-gnueabihf- all
