Merge tag 'kbuild-fixes-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild

Pull Kbuild fixes from Masahiro Yamada:

 - Exclude kallsyms_seqs_of_names from kallsyms to fix build error

 - Fix 'make kernelrelease' for external module builds

 - Get the Debian source package compilable again

 - Fix the wrong uname when Debian packages are built with the
   KDEB_PKGVERSION option

 - Fix superfluous CROSS_COMPILE when building Debian packages

 - Fix RPM package build error when KCONFIG_CONFIG is set

 - Use 'git archive' for creating source tarballs

 - Remove the scripts/list-gitignored tool

* tag 'kbuild-fixes-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild:
  kbuild: use git-archive for source package creation
  kbuild: rpm-pkg: move source components to rpmbuild/SOURCES
  kbuild: deb-pkg: use dh_listpackages to know enabled packages
  kbuild: deb-pkg: split image and debug objects staging out into functions
  kbuild: deb-pkg: set CROSS_COMPILE only when undefined
  kbuild: deb-pkg: do not take KERNELRELEASE from the source version
  kbuild: deb-pkg: make debian source package working again
  Makefile: Make kernelrelease target work with M=
  kconfig: Update config changed flag before calling callback
  kallsyms: add kallsyms_seqs_of_names to list of special symbols
