We saw too many cases where headers was not assigned to unifdef-y
after introducing "#ifdef __KERNEL__".
So we integrated the install and unifdef step to avoid this.
And with the header stuff in kbuild redesigned the cost was acceptable to do so.

When I get some spare time I plan to re-implement the unifdef tool
so it does exactly what we want it to do so we can skip the
perl/unifdef stuff we have today.

And I should sent a patch to Linus to get rid of unifdef-y so not to
confuse people.
