Does "makeoptions WITH_CTF=yes" actually work?

Can you also try a "makeoptions WITH_CTF=yes" in your KERNCONF
and see if the results are as expected?  How was r206082 tested?  I'm
trying to figure out the differences, if any, between your build setup and

I got rid of the @ in front of all the CTF commands in all the .mk files.  I
could see that NO_CTF was 1 and so the ctfconvert after || wouldn't

[ -z "${CTFCONVERT}" -o -n "${NO_CTF}" ] || ${CTFCONVERT} ${CTFFLAGS} ${.TARGET}

[ -z "ctfconvert" -o -n "1" ] || ........

Do you see anything different if you remove all the @'s?

I tried this:
# ctfdump /usr/obj/usr/src/sys/GENERIC/kernel
/usr/obj/usr/src/sys/GENERIC/kernel does not contain .SUNW_ctf data
