I've just upgraded my amd64 machine as described at the end of build(7)
with a little arrangement:

env - PATH=/sbin:/bin:/usr/sbin:/usr/bin __MAKE_CONF=/dev/null sh -c '
    make buildworld
    make buildkernel KERNCONF=FOO
    make installkernel KERNCONF=FOO
    make installworld
    MACHINE_ARCH=x86_64 make upgrade
'

(the first line is to get rid of extra env variables or /etc/make.conf)
then rebooted, and now make command reports these variables correctly:
    $ cd
    $ env - PATH=$PATH make -V MACHINE_ARCH -V MACHINE -V MACHINE_PLATFORM
    x86_64
    x86_64
    pc64

so if you're running new kernel and still need those environment variables
set to x86_64, maybe you need to build and install it WITHOUT those
environment variables set.

Cheers.
