It was particular to the mpc8315e config.

Runtime on the target is fine, since this is all well known
and working (we've had SPE/e500/e500v2 BSPs working for
quite some time), the issue was specific to -Os and gcc 4.5
bootstrap building.

These have all largely been resolved now, and a minor kernel
patch has the powerpc kernel boot code building and working,
and cleanups can happen in our post yocto 0.9 efforts.

Cheers,

Bruce
