Merge tag 'kconfig-v4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild

Pull Kconfig updates from Masahiro Yamada:
 "Kconfig now supports new functionality to perform textual
  substitution. It has been a while since Linus suggested to move
  compiler option tests from makefiles to Kconfig. Finally, here it is.

  The implementation has been generalized into a Make-like macro
  language.

  Some built-in functions such as 'shell' are provided. Variables and
  user-defined functions are also supported so that 'cc-option',
  'ld-option', etc. are implemented as macros.

  Summary:

   - refactor package checks for building {m,n,q,g}conf

   - remove unused/unmaintained localization support

   - remove Kbuild cache

   - drop CONFIG_CROSS_COMPILE support

   - replace 'option env=' with direct variable expansion

   - add built-in functions such as 'shell'

   - support variables and user-defined functions

   - add helper macros as as 'cc-option'

   - add unit tests and a document of the new macro language

   - add 'testconfig' to help

   - fix warnings from GCC 8.1"
