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"
