There are quite few tests online for floating-point testing, such as
http://www.tybor.com/ or
http://www.math.utah.edu/~beebe/software/ieee/. I bet you can find
many more.

Another idea is to install some CAS from pkgsrc and run its own test
suite, if it has one. E.g., math/maxima.

Last, we have a math test suite for libm. Here you can find
information on how to deploy it:
http://netbsd-soc.sourceforge.net/projects/mathlib/#_how_to_get_you_started

You could give it a shot and compare your results with those for other
architectures:
http://leaf.dragonflybsd.org/~beket/logs/NetBSD/

If there are many more failures in MIPS than in other archs, that
could be indicative of a problem in MIPS.
