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".
