Everything in Documentation should be built against the headers in the
kernel source tree due to the dep on CONFIG_HEADERS_CHECK.
The patch that added this code was in the 3.12 tree
(https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Makefile?id=8d49751),
did it not work when it was first merged?
What was the exact command you used to compile this code?
Did you make sure check_headers was run first?

Thanks,

Peter
