    ARC: Add guard macro to uapi/asm/unistd.h · 97bc386f

    Chen originally proposed this as "right thing to do" however I
    actually ran into this when building perf tools. Some of the utils
    include unistd.h as well as linux/unistd.h. Since -I includes kernel
    headers too, we end up including the ARC unistd.h twice, leading to
    redefinition nwarnings.

    Verified that make headers_install works fine with this.
