MIPS: fix endianess handling
Make endianess of target CPU configurable. Use the new config option for dbau1550_el and pb1000 boards. Adapt linking of standalone applications to pass through endianess options to LD. Build tested with: - ELDK 4 mips_4KC- and mips4KCle - Sourcery CodeBench Lite 2011.03-93 With this patch all 26 MIPS boards can be compiled now in one step by running "MAKEALL -a mips".
