Subject: linux-next: build failure after merge of the kbuild tree

Hi all,

After merging the kbuild tree, today's linux-next build (powerpc
ppc44x_defconfig) failed like this:

cc1: fatal error: opening output file arch/powerpc/boot/dts/.ebony.dtb.dts.tmp: No such file or directory

and directory arch/powerpc/boot/dts/ does, indeed, not exist in the
separate object directory.

Caused by commit

  ea4679253288 ("kbuild: always create directories of targets")

at least, reverting that commit makes the build work again.
