KERN isn't very good either. "@" is better once the "@" symlink is
created. "@" currently isn't very useful. It could be replaced by
$S or ${KERN}. I implemented it because its implementation almost
shows how to set ${KERN} automatically and was almost free (it shares
code with the automatic setting of the "machine" symlink).

They are apparently using $S because $S is used in the kernel makefiles
that the foo_if.h rules were copied from.
