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"
