I'm afraid there are few people who tried mips SOFTFLOAT code
on big endian environment. (anyone tried it on alchemy?)

I guess you would have to add some #if _BYTE_ORDER
like locore_mips3.S to swap high/low words in some
64bit functions.

BTW, do NEC VR41xx processors work properly on big endian?
I heard a rumour that some embedded peripherals didn't work
on big endian since they were designed for WindowsCE.
