Update MIPS configuration rules.
Add a configuration choice for the NaN format on MIPS (either the standard (legacy) format or the newer IEEE 2008 format. Change how CPU_LDFLAGS are set for MIPS. Use the same value as CPU_CFLAGS since CC is used to do linking. This ensures consistency between compiles and links and adds support for N32 ABI to linking.
