#     Merge tag 'kbuild-v5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
#     
#     Pull Kbuild updates from Masahiro Yamada:
#     
#      - do not generate unneeded top-level built-in.a
#     
#      - let git ignore O= directory entirely
#     
#      - optimize scripts/kallsyms slightly
#     
#      - exclude DWARF info from *.s regardless of config options
#     
#      - fix GCC toolchain search path for Clang to prepare ld.lld support
#     
#      - do not generate modules.order when CONFIG_MODULES is disabled
#     
#      - simplify single target rules and remove VPATH for external module
#        build
#     
#      - allow to add optional flags to dpkg-buildpackage when building
#        deb-pkg
#     
#      - move some compiler option tests from Makefile to Kconfig
#     
#      - various Makefile cleanups
#
