Merge tag 'kconfig-v4.19' of git://git./linux/kernel/git/masahiroy/linux-kbuild

Pull Kconfig updates from Masahiro Yamada:

 - show clearer error messages where pkg-config is needed, but not
   installed

 - rename SYMBOL_AUTO to SYMBOL_NO_WRITE to reflect its semantics

 - create all necessary directories by Kconfig tool itself instead of
   Makefile

 - update the .config unconditionally when syncconfig is invoked

 - use 'include' directive instead of '-include' where
   include/config/{auto,tristate}.conf is mandatory

 - do not try to update the .config when running install targets

 - add .DELETE_ON_ERROR to delete partially updated files

 - misc cleanups and fixes
