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fixes from Masahiro Yamada: - fix linker script regression caused by dead code elimination support - fix typos and outdated comments - specify kselftest-clean as a PHONY target - fix "make dtbs_install" when $(srctree) includes shell special characters like '~' - Move -fshort-wchar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 fixdep: trivial: typo fix and correction kbuild: trivial cleanups on the comments kbuild: linker script do not match C names unless LD_DEAD_CODE_DATA_ELIMINATION is configured
