description:
Add a NOCOMPAT kernel definition to serve as a baseline for getting
the incremental COMPAT_xx options working.

While here, add some additional "requires COMPAT_xxx" to some of the
options in GENERIC

+# The machine description file can be customised for your specific
+# machine to reduce the kernel size and improve its performance.
+#
+# For further information on compiling NetBSD kernels, see the config(8)
+# man page.

+# For further information on hardware support for this architecture, see
