I have some questions about your configuration.

In your attached config.txt, you have things like:

    CT_WORK_DIR="[WORK_DIR]"

and an arch suffix "-e6500" (iow: -e6500powerpc64-unknown-linux-gnu)
doesn't really make sense to me.

I'm surprised this config works at all.

Are you making this config with another external tool, such as
buildroot or a custom wrapper script? That may make some of my
confusion go away.

(PS, I have an updated config I'll post after I test it.)
