I believe the location of ctfconvert which is used is broken so unless
your system has a version of ctfconvert which includes the attr fix
you will always get this :(

The reason I believe this is:-
make buildenv
Entering world for amd64:amd64
# which ctfconvert
/usr/bin/ctfconvert
# which cc
/usr/obj/usr/home/smh/freebsd/base/head/tmp/usr/bin/cc

So where I believe ctfconvert should be being picked up from the
toolchain its not.

I've had a quick dig in the Makefile's but I don't know them well at
all and so couldn't find an easy fix :(

The workaround I'm using is:
make -DNO_CTF buildkernel

If someone who better knows the make system could suggest a patch
so that ctfconvert (and potentially other tools) are build and
detected in the toolchain that would be most appreciated.
