That's because Kbuild injects it via command line flag `-include`.
(Well, it injects compiler_types.h which includes this).  If part of
the tree reset KBUILD_CFLAGS, that `-include` gets dropped.  I don't
think there's anything wrong with manually including it and adding `-I
<path>` (capital i) if needed.
