Which distro are you testing on?

Isn't this makefile part of iproute2?
Can you build iproute on this platform?

Probably a distro-specific backport problem - check how come sg_dma_len is not defined.
I see this on upstream 2.6.16
	asm-powerpc/scatterlist.h:#define sg_dma_len(sg) ((sg)->dma_length)
