PPC e500v2 seems to be not properly supported in glibc. The current sample
uses eglibc, which has some fixes/enhacements for e500v2, bundled in the
ports addon.

I could not reproduce that on my machine here, with your .config but only
6 parallel jobs. Try lowering the number of // jobs (eg. try with one, and
see if it still breaks). If it works with 1 job, then it's the // build
that is broken. If it still does not, then there might be an issue on your
build environment.

I tried to build, and it passed the "C library headers & start files" step.
It broke later, though.

I can't remember where (maybe earlier on this list, search the archives), but
I seem to recall that PPC e500v2 requires eglibc.
