It looks like a simplification but there is actually a reason why it is done with a temporary fil in this way. Consider a kernel build that is being terminated with ctrl-c in the middle. If we when ctrl-c are hit are doing the final steps of genksyms then we will next time we type make consider all done and we will not redo the modversioning part of the rule because we have an updated .o file. We have this issue in other places in the build system but I have not audited the use of redirects yet. But applying your patch would introduce yet another place where we have such an issue and we want to get rid of the spots where hitting ctrl-c can leave us with an inconsistent build. So I will not apply this patch.
