Hmm don't have klds to be compiled with the same cc as the kernel
i.e. the system cc?  You could try to mv away files/patch-Makefile.freebsd
(which actually is a leftover from times when kqemu was still built
inside the qemu tree, where it was necessary to get kqemu to build
on systems where qemu's CC differed from the system cc.)  If this
works, we can probably remove that patch now as whoever sets CC on a
kdl port should know what he's doing... :)
