The URL above also says: "Tests are intended to be run after building,
installing and booting a kernel".
Please build selftests with installed kernel headers corresponding to the
Alternatively, tools/testing/selftests/lib.mk could be extended

I think this is fixed in the selftest tree itself now (though
differently), in that it depends on having build the headers first.
Anyway, please let me know if this is still a problem, and I'll take
another look (and hopefully I also won't lose the thread for a year...)
