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.
