That's not the way to enable a debugging kernel.

Set

makeoptions "-g"

in the kernel configuration file, config, make depend, make, make install.

That will install a stripped kernel but give you a kernel.debug in the
compile directory you can use for crash dumps.

See the Handbook section on debugging crash dumps for more information.
