  This further simplify the 'make' commands, only require an ARCH now.

Almost all distributions provide toolchains for i386, x86_64, arm64,
arm, mips, riscv32, riscv64 and s390x.

If can not find toolchains from the distribution repositories, we can
download them from https://mirrors.edge.kernel.org/pub/tools/crosstool/
and then customize CROSS_COMPILE_<ARCH> for the testing.
