I support this is as most of the times when the latest headers aren't
installed in the system. Hence the build of all those kselftests would fail
which require the recently added macros. There is no workaround to build
those tests until `make headers` is done or the latest headers are
installed. The former is easier.
If we just turn this into warning, most people reporting issues with `make
headers` would go away. They will be able to build all those kselftest
which don't require latest headers. For example mincore kselftest gets
build without KHDR_INCLUDES. In case people want to build failing tests,
they should add #ifdefs to the tests and submit patches which is idea 4.
