backports: support make clean/mrproper

The kernel's "make clean" will recurse into subdirectories, even
into those that aren't enabled in Kconfig. Thus, the previous
trick of changing symbols from CONFIG_* to IMPOSSIBLE_* doesn't
work any more. Change this to comment out the lines instead and
then support "make clean" and "make mrproper".
