>From /usr/src/sys/conf/NOTES :

# This allows you to actually store this configuration file into
# the kernel binary itself, where it may be later read by saying:
#    strings -n 3 /boot/kernel/kernel | sed -n 's/^___//p' > MYKERNEL
options   INCLUDE_CONFIG_FILE     # Include this file in kernel

Also check out /usr/src/sys/i386/conf/NOTES
Replace i386 with your arch.
