#     Merge tag 'kbuild-v5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
#     
#     Pull Kbuild updates from Masahiro Yamada:
#     
#      - Add HOSTPKG_CONFIG env variable to allow users to override pkg-config
#     
#      - Support W=e as a shorthand for KCFLAGS=-Werror
#     
#      - Fix CONFIG_IKHEADERS build to support toybox cpio
#     
#      - Add scripts/dummy-tools/pahole to ease distro packagers' life
#     
#      - Suppress false-positive warnings from checksyscalls.sh for W=2 build
#     
#      - Factor out the common code of arch/*/boot/install.sh into
#        scripts/install.sh
#     
#      - Support 'kernel-install' tool in scripts/prune-kernel
#     
#      - Refactor module-versioning to link the symbol versions at the final
#        link of vmlinux and modules
#     
#      - Remove CONFIG_MODULE_REL_CRCS because module-versioning now works in
#        an arch-agnostic way
#     
#      - Refactor modpost, Makefiles
#
