Maybe somebody can change this to be able to include in-tree headers directly?

If the above works, maybe the files in tools/include/* is not
necessary any more, just use the in-tree headers to compile
the user space app?

Or I missed something here?

Besides above, had you tested this with `make O=...`?

You are right, the generated/autoconf.h is in another directory
with `make O=...`.

Any nice idea to fix the above problem?
