+ 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.
