It seems if I modify test_math.cxx I do get the test_math.o rebuilt 
properly, but a rebuild of the test harness  vnl_test_all doesn't 
happen. In order to get the test harness rebuilt, I need to:
vi /.../InsightBuild/Utilities/vxl/core/vnl/tests/test_math.cxx
rm /.../InsightBuild/Utilities/vxl/core/vnl/tests/vnl_test_all
cd /.../InsightBuild
make

If I don't remove vnl_test_all, it doesn't get rebuilt.
