Paul Gortmaker 65f6f092a6 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:

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.
