    main/lz4: fix 2x speed degradation on x86* · df7f7f3f
    alpine-mips-patches authored
    This is exactly the same memcpy()-in-hot-path xxHash problem, see
    community/xxhash commit log for details.
    
    The bug makes "lz4 -1" or "lz4 -t" twice slower on x86_64 however
    "lz4 -9" is barely affected (do not use "lz4 -b" for benchmarking
    this change since it does not calculate the checksum).
    
    Other aport changes:
     - use short and fast "make check" (unlike extensive "make test")
       for pre-v7 ARM architectures.
