I ran buildkernel again and the patch doesn't work as-is if it's
not defined in the environment as it isn't one of the variables that's
passed through by default via make to buildkernel when running
config(8), so one needs to modify Makefile.inc1 as well in order for
things to function properly as described with my patch.
