I have read about an option to include the configuration file with the
kernel.  From my 4.9-stable /usr/src/sys/i386/conf/LINT file:

# 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 /kernel | sed -n 's/^___//p' > MYKERNEL
#
options         INCLUDE_CONFIG_FILE     # Include this file in kernel

Not useful unless you've used it, which is not the default case.
