Documentation/mic/mpssd: don't build x86 userspace when cross compiling
The following was seen in linux-next build coverage, which is somewhat unique since it uses powerpc host to cross compile x86: Documentation/mic/mpssd/mpssd.c:93:10: error: braced-group within expression allowed only inside a function Documentation/mic/mpssd/mpssd.c:96:10: error: braced-group within expression allowed only inside a function Documentation/mic/mpssd/mpssd.c:113:10: error: braced-group within expression allowed only inside a function Documentation/mic/mpssd/mpssd.c:116:10: error: braced-group within expression allowed only inside a function Documentation/mic/mpssd/mpssd.c:119:3: error: initializer element is not constant Documentation/mic/mpssd/mpssd.c:119:3: error: (near initialization for 'virtnet_dev_page.host_features') Documentation/mic/mpssd/mpssd.c:146:10: error: braced-group within expression allowed only inside a function Documentation/mic/mpssd/mpssd.c:149:3: error: initializer element is not constant Documentation/mic/mpssd/mpssd.c:149:3: error: (near initialization for 'virtblk_dev_page.host_features') Documentation/mic/mpssd/mpssd.c:151:3: error: initializer element is not constant Documentation/mic/mpssd/mpssd.c:151:3: error: (near initialization for 'virtblk_dev_page.blk_config.seg_max') Documentation/mic/mpssd/mpssd.c:152:3: error: initializer element is not constant Documentation/mic/mpssd/mpssd.c:152:3: error: (near initialization for 'virtblk_dev_page.blk_config.capacity') 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.
