Subject: [PATCH] Add CONFIG_HEADERS_CHECK option to automatically run 'make
 headers_check'

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.
