buildkernel: make[2]: exec(ctfconvert) failed (No such file or directory)

Hi!

I'm trying to build CURRENT r273800 with an empty
(actually nonexisting) /etc/src.conf when it previously had contained:

WITHOUT_MODULES=dtrace
WITHOUT_CDDL=

# uname -a
FreeBSD onyx.thanelange.no 11.0-CURRENT FreeBSD 11.0-CURRENT #7
r273066M: Sun Oct 19 20:12:57 CEST 2014
root_at_onyx.thanelange.no:/usr/obj/usr/src/sys/ONYX  amd64

# rm -rf /usr/obj/*
# make buildworld buildkernel

The world build succeeds fine, but the kernel build fails with:

This tells me that buildworld succeeded in building the ctfconvert
binary, but buildkernel is not picking up the newly built tool.

Any advice on getting around this?

I would prefer not having to install the new world before building and
installing the new kernel.

Best regards,
