Merge tag 'kbuild-v5.2-2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
Pull more Kbuild updates from Masahiro Yamada:
- remove unneeded use of cc-option, cc-disable-warning, cc-ldoption
- exclude tracked files from .gitignore
- re-enable -Wint-in-bool-context warning
- refactor samples/Makefile
- stop building immediately if syncconfig fails
- do not sprinkle error messages when $(CC) does not exist
- move arch/alpha/defconfig to the configs subdirectory
- remove crappy header search path manipulation
- add comment lines to .config to clarify the end of menu blocks
- check uniqueness of module names (adding new warnings intentionally)
