    Documentation/mic/mpssd: don't build x86 userspace when cross compiling · 65f6f092

    The following was seen in linux-next build coverage, which is somewhat
    unique since it uses powerpc host to cross compile x86:

    make[5]: *** [Documentation/mic/mpssd/mpssd.o] Error 1
    
    Since it is building /usr/sbin/mpssd and /usr/sbin/micctrl
    for x86_64 and the original authors indicated[1] that:
    
       MIC card is expected to work with x86_64 host, not with ppc64.
       We have never compiled on ppc host..
    
    so it probably makes sense to just skip building these userspace
    programs when we are cross compiling.
