kbuild: remove CONFIG_CROSS_COMPILE support
Kbuild provides a couple of ways to specify CROSS_COMPILE: [1] Command line [2] Environment [3] arch/*/Makefile (only some architectures) [4] CONFIG_CROSS_COMPILE [4] is problematic for the compiler capability tests in Kconfig. CONFIG_CROSS_COMPILE allows users to change the compiler prefix from 'make menuconfig', etc. It means, the compiler options would have to be all re-calculated everytime CONFIG_CROSS_COMPILE is changed. To avoid complexity and performance issues, I'd like to evaluate the shell commands statically, i.e. only parsing Kconfig files. I guess the majority is [1] or [2]. Currently, there are only 5 defconfig files that specify CONFIG_CROSS_COMPILE. arch/arm/configs/lpc18xx_defconfig arch/hexagon/configs/comet_defconfig arch/nds32/configs/defconfig arch/openrisc/configs/or1ksim_defconfig arch/openrisc/configs/simple_smp_defconfig Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Kees Cook <keescook@chromium.org>
