This was an amd64 -> powerpc64 cross build
(kernel-toolchain buildkernel and separately buildworld).
[Note: Anything dependent on throwing C++ exceptions in
code generated by clang++ 3.9.1 is broken.]

PowerMac G5 specific workaround for unreliable booting
that is from a openfirmware vs. FreeBSD interaction
in the standard FreeBSD build. The ddb items are not
