Subject: Add CONFIG_HEADERS_CHECK option to automatically run 'make headers_check'
From: David Woodhouse <dwmw2@xxxxxxxxxxxxx>
In order to encourage people to notice when they break the exported
headers, add a config option which automatically runs the sanity checks
when building vmlinux. That way, those who use allyesconfig will notice
failures.

+ This option will extract the user-visible kernel headers whenever
+ building the kernel, and will run basic sanity checks on them to
+ ensure that exported files do not attempt to include files which
+ were not exported, etc.

+ If you're making modifications to header files which are
+ relevant for userspace, say 'Y', and check the headers
+ exported to $(INSTALL_HDR_PATH) (usually 'usr/include' in
+ your build tree), to make sure they're suitable.
