Currently a build with CONFIG_E200=y will fail with: Error: invalid switch -me200 Error: unrecognized option -me200 Upstream binutils has never supported an -me200 option. Presumably it was supported at some point by either a fork or Freescale internal binutils. We can't support code that we can't even build test, so drop the addition of -me200 to the build flags, so we can at least build with CONFIG_E200=y.

Thanks for the patch; this should make randconfig builds not pick this non-buildable config. Reviewed-by: Nick Desaulniers <ndesaulniers@google.com>
