    tests: Tolerate greater rendering differences on all non-x86_64
    
    Previously, this used 32-bit vs. 64-bit to discriminate, with
    32-bit architectures allowed to deviate more from the reference
    rendering (mainly because the i387 FPU used on baseline i386
    builds has excess precision in its FP registers). However, one
    test also produces a colour channel difference of 3 on
    mips64el, a 64-bit architecture; tolerate this too.
