Prelinker is being run within the rootfs, so the /etc/prelink.conf being used is
the one inside of the image -- NOT the system version.

I would suspect that the cross-prelinker rtld emulation is likely setup for the
LSB style library paths and may be causing some of the problems.

I'd suggest simply disabling prelink and getting everything to work first.. once
it does we can work through any prelinker issues.  (Prelink on PPC64 hasn't been
tested within the oe-core environment.. so it could very well have issues beyond
the ld.so path.)
