Merge branch 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild

Pull kbuild updates from Michal Marek:
 "Kbuild changes for v3.16-rc1:

   - cross-compilation fix so that cc-option is testing the right
     compiler
   - Fix for make defconfig all
   - Using relative paths to the object and source directory where
     possible, plus fixes for the fallout of the change
   - several cleanups in the Makefiles and scripts

  The powerpc fix is from today, because it was only discovered
  recently.  The rest has been in linux-next for some time"
