Recognize a %VERSREQ=nnnnn string in the system Makefile. Both config(8)
and the kernel will have a 'config interface version number'. If an
incompatable change is made to the kernel that requires a rebuild of
config(8) (such as the cam devtab stuff), then the version number would be
bumped in both places. If a user neglects to rebuild config, then they
will get a nagging (but non-fatal) warning that they need to rebuild
config.
