+Disable some image comparison tests on architectures such as i686
+where intermediate floating-point operations are done with 80-bit long
+doubles, and typically later rounded to 64-bit doubles.  This double
+rounding causes small differences in the resulting pixel values
+compared with other architectures, causing the image comparisons to
+fail.
