Warner Losh f36c2bbe0c Remove the insistance on having a device.hints. This was a seat belt
for those upgrading from 4.x -> 5.x.  It is therefore no longer
necessary because it is installed on 5.x and 6.x and one has to
upgrade from 6.x -> current, or at the very least 5.x (although not
supported, it can be made to work).

# $FreeBSD$
# Part of a unified Makefile for building kernels. This part includes all
# the definitions that need to be after all the % directives except %RULES
# and ones that act like they are part of %RULES.
#
# Most make variables should not be defined in this file. Instead, they
# should be defined in the kern.pre.mk so that port makefiles can
# override or augment them.
# In case the config had a makeoptions DESTDIR...
