    kbuild: remove CONFIG_CROSS_COMPILE support · f1089c92
    Masahiro Yamada authored
    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
