That is exactly what I found confusing. I tried both with and without
CTF in my kernel config file and the build still failed.
grep CTF /sys/amd64/conf/ernst_new
#makeoptions WITH_CTF=1 # Run ctfconvert(1) for DTrace support
#options DDB_CTF # Kernel ELF linker loads CTF data
I also have
makeoptions MODULES_OVERRIDE="cpuctl msdosfs pseudofs filemon"
If I move ctfconvert away then I see this error:
cd /usr/src; make buildkernel
--------------------------------------------------------------
>>> Kernel build for ernst_new started on Thu Apr 9 08:51:06 CEST 2020

===> ernst_new

>>> stage 1: configuring the kernel
--------------------------------------------------------------
Kernel build directory is /home/garyj/obj/usr/src/amd64.amd64/sys/ernst_new
Don't forget to do ``make cleandepend && make depend''
--------------------------------------------------------------
>>> stage 2.3: build tools

sh: ctfconvert: not found
*** [cpuctl.o] Error code 127
make[4]: *** cpuctl.o removed
make[4]: stopped in /usr/src/sys/modules/cpuctl
.ERROR_TARGET='cpuctl.o'
.ERROR_META_FILE='/home/garyj/obj/usr/src/amd64.amd64/sys/ernst_new/modules/usr/src/sys/modules/cpuctl/cpuctl.o.meta'
So, without ctfconvert installed buildkernel ALWAYS fails to build the
modules no matter what CTF options are used in the kernel config file.
In contrast, buildworld does still work without ctfconvert.
