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.
