Since I've been fixing build issues for ColdFire, this patch adds a
math-tests.h file for ColdFire, reflecting the lack of support for
exceptions and rounding modes for soft float.  I think it is logically
correct, but have not tested it beyond build-many-glibcs.py for both
hard and soft float.

Committed.
