This patch results in:

/usr/bin/env: invalid option -- 'S'
Try '/usr/bin/env --help' for more information.
init/Kconfig:39: syntax error
init/Kconfig:38: invalid statement
scripts/kconfig/Makefile:80: recipe for target 'defconfig' failed

when using:

env (GNU coreutils) 8.28

or any other version of "env" which doesn't support "-S".
