    fuzz: build without AddressSanitizer, by default
    
    We already have a nice --enable-sanitizers option to enable
    AddressSanitizer. There is no reason to duplicate and force this
    functionality in --enable-fuzzing. In the future, if more sanitizers are
    added to --enable-sanitizers, it might be impossible to build with both
    --enable-sanitizers and --enable-fuzzing, since not all sanitizers are
    compatible with libFuzzer. In that case, we could enable ASAN with
    --extra-cflags="-fsanitize=address"
