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

Pull kbuild updates from Michal Marek:
 - fix for make headers_install argv explosion with too long path
 - scripts/setlocalversion does not call git update-index needlessly
 - fix for the src.rpm produced by make rpm-pkg.  The new make
   image_name can be useful also for other packaging tools.
 - scripts/mod/devicetable-offsets.o is not rebuilt during each make run
 - make modules_install dependency fix
 - scripts/sortextable portability fix
 - fix for kbuild to generate the output directory for all object files
   in subdirs.
 - a couple of minor fixes

* 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
  kbuild: create directory for dir/file.o
  tools/include: use stdint types for user-space byteshift headers
  Makefile: Fix install error with make -j option
  Fix a build warning in scripts/mod/file2alias.c
  improve modalias building
  scripts/mod: Spelling s/DEVICEVTABLE/DEVICETABLE/
  kbuild: fix error when building from src rpm
  scripts/setlocalversion on write-protected source tree
  Makefile.lib: align DTB quiet_cmd
  kbuild: fix make headers_install when path is too long
