Can you please share the output of:

$ ctfdump -t SAMWISE/adiantum.o
$ ctfdump -t SAMWISE/netbsd
$ config -x SAMWISE/netbsd

in your clean build?

If you delete the SAMWISE build directory and rebuild it, do you get
the same output?

Evidently I never noticed this because I always build with MKDEBUG=yes
(or MKDEBUGKERNEL=yes) which renders it unnecessary.

I think maybe we should delete the makeoptions lines in the kernel
configs, and set MKDEBUG=yes or at least MKDEBUGKERNEL=yes by default.
