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

Pull kbuild updates from Michal Marek.

Fixed up nontrivial merge conflict in Makefile as per Stephen Rothwell
and linux-next (and trivial arch/sparc/Makefile changes due to removed
sparc32 logic).

* 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
  mips: Fix KBUILD_CPPFLAGS definition
  kbuild: fix ia64 link
  kbuild: document KBUILD_LDS, KBUILD_VMLINUX_{INIT,MAIN} and LDFLAGS_vmlinux
  kbuild: link of vmlinux moved to a script
  kbuild: refactor final link of sparc32
  kbuild: drop unused KBUILD_VMLINUX_OBJS from top-level Makefile
  kbuild: Makefile: remove unnecessary check for m68knommu ARCH
