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.

Patch by Mark H Weaver <mhw@netris.org>.
