Merge tag 'kbuild-v5.3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild

Pull more Kbuild updates from Masahiro Yamada:

 - match the directory structure of the linux-libc-dev package to that
   of Debian-based distributions

 - fix incorrect include/config/auto.conf generation when Kconfig
   creates it along with the .config file

 - remove misleading $(AS) from documents

 - clean up precious tag files by distclean instead of mrproper

 - add a new coccinelle patch for devm_platform_ioremap_resource
   migration

 - refactor module-related scripts to read modules.order instead of
   $(MODVERDIR)/*.mod files to get the list of created modules

 - remove MODVERDIR

 - update list of header compile-test

 - add -fcf-protection=none flag to avoid conflict with the retpoline
   flags when CONFIG_RETPOLINE=y

 - misc cleanups
