Ok, I have an updated nand_spl/board/freescale/mx31pdk/Makefile below.
It works for both in-tree and out of tree builds. I'm not particularly
happy with the "$(obj)%.o: $(SRCTREE)..." lines but I couldn't make it
work otherwise. Perhaps someone has a better solution.

I know gmail will mangle at least one long line, but I'll update my
patch series later as well.

Thanks, Magnus
