Merge tag 'kbuild-fixes-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
Pull Kbuild fixes from Masahiro Yamada:
- fix -gz=zlib compiler option test for CONFIG_DEBUG_INFO_COMPRESSED
- improve cc-option in scripts/Kbuild.include to clean up temp files
- improve cc-option in scripts/Kconfig.include for more reliable
compile option test
- do not copy modules.builtin by 'make install' because it would break
existing systems
- use 'userprogs' syntax for watch_queue sample
* tag 'kbuild-fixes-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild:
samples: watch_queue: build sample program for target architecture
Revert "Makefile: install modules.builtin even if CONFIG_MODULES=n"
scripts: Fix typo in headers_install.sh
kconfig: unify cc-option and as-option
kbuild: improve cc-option to clean up all temporary files
Makefile: Improve compressed debug info support detection
