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.

buildsys: fix IS_IN_lib* for out-of-tree builds

41537a770b46f2376e74af58ba4885749339e81e erroneously stripped the top_builddir off the per-directory flag setting which works fine for in-tree builds but is not correct for O= Just use the full path of the target files to apply the flags to fix that thinko.
