The intention of these changes was to generate more compiliation coverage for code in Documentation/ The underlying issue is that this doesn't work for cross-compiling because kbuild doesn't have cross-compile support for userspace code. I submitted a patch to disable building Documentation when cross-compiling, as the consensus in the thread that resulted in that patch (https://lkml.org/lkml/2014/10/8/510) was that implementing targetprogs in kbuild was not currently worth it. I can try to take a crack at adding targetprogs support, but I'm rather busy right now, so it may take a little while. Thanks, Peter
