Adding the following few lines fixes the problems with the headers (they 
are normally defined by gcc)...
I am not sure that is all that is needed (the rest might just be me 
doing bad things in my driver) but since they are mips specific I think 
arch/mips/Makefile would be the right place for them:

CHECKFLAGS    += -D__mips__
ifdef CONFIG_MIPS32
CHECKFLAGS    += -D_MIPS_SZLONG=32
else
CHECKFLAGS    += -D_MIPS_SZLONG=64
endif
ifdef CONFIG_CPU_LITTLE_ENDIAN
CHECKFLAGS    += -D__MIPSEL__
else
CHECKFLAGS    += -D__MIPSEB__
endif
