Here I'm missing a step in your desription: as you noted,
/usr/lib/libxml2.so* is part of the ELDK, so what do you need
libxml2-devel for?

So just ignore the dependency - try "${CROSS_COMPILE}rpm --nodeps -i ..."

Are you sure that you used sane compiler options? Keep in mind that
the 85xx don't have a FPU, and that the SPE is used for floating point
calculations.
