    These two tests FAIL on powerpc64le-linux (and I assume on all other
    -funsigned-char defaulting targets).
    
    The following patch fixes that, tested on powerpc64le-linux and
    x86_64-linux (-m32/-m64); on x86_64 also tested before/after with
    -funsigned-char.
    
    Ok for trunk?
