Merge tag 'kbuild-v6.17-2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild

Pull Kbuild updates from Masahiro Yamada:
"This is the last pull request from me.

I'm grateful to have been able to continue as a maintainer for eight
years. From the next cycle, Nathan and Nicolas will maintain Kbuild.

- Fix a shortcut key issue in menuconfig

- Fix missing rebuild of kheaders

- Sort the symbol dump generated by gendwarfsyms

- Support zboot extraction in scripts/extract-vmlinux

- Migrate gconfig to GTK 3

- Add TAR variable to allow overriding the default tar command

- Hand over Kbuild maintainership"
