build custom kernel under FreeBSD 12

[Ryan Stone]

How are you setting MAKEOBJDIRPREFIX?  It needs to be set in your
environment, i.e.

$ export MAKEOBJDIRPREFIX=$HOME/obj
$ make buildkernel

Trying 'make MAKEOBJDIRPREFIX=$HOME/obj buildkernel' will fail in
strange ways due to how make passes arguments to sub-makes.
