The first three fix a warning observed for `mrproper` targets when $(CROSS_COMPILE_COMPAT)gcc is not in the $PATH. The fourth makes is so that CROSS_COMPILE_COMPAT is not necessary to select COMPAT_VDSO when using clang+lld. Based on arm64/linux.git/for-next/misc. Changes v1 -> v2: * Fix binutils version numbers in 1/4 as per Christian. * Add new patch 2/4 as per Arnd. * Rewrite 3/4 to use redirection of stderr to /dev/null, as per Masahiro. * Add parens and update commit message of 4/4 as per Nathan.
