Merge tag 'kbuild-fixes-v4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild

Pull Kbuild fixes from Masahiro Yamada:

 - fix linker script regression caused by dead code elimination support

 - fix typos and outdated comments

 - specify kselftest-clean as a PHONY target

 - fix "make dtbs_install" when $(srctree) includes shell special
   characters like '~'

 - Move -fshort-wchar to the global option list because defining it
   partially emits warnings

* tag 'kbuild-fixes-v4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild:
  kbuild: update comments of Makefile.asm-generic
  kbuild: Do not use hyphen in exported variable name
  Makefile: add kselftest-clean to PHONY target list
  Kbuild: use -fshort-wchar globally
