Sorry, but I prefer to ask before trying to understand this 'make -C scripts
unifdef' alone.

Does really this single change in the kernel builder makes the $out path have
anything different (have the unifdef script, in this case)? It looks as if it
would only build unifdef, but not install it. And isn't unifdef always built
when building the kernel target?
