Shouldn't this be a separate patch?
The one issue with this is that only newer versions of dtc support the
-i option. The version packaged with most distros won't support it.
That'll mean something like "MAKEALL -a arm" is going to fail for a lot
of people without some kind of explicit action (i.e. manually installing
a newer version of dtc).
That's why I suggested switching from /include/ to #include, and adding
the include path to the cpp command rather than dtc.
