It depends: sometimes it is prudent to add the code behind an ifdeffery
first but have it not being buildable so that you don't have to deal
with build breakages but rather concentrate on adding the facilities
first.
And you add the Kconfig item only in the end where everything is in
place and it should build properly then.
