I think it would make sense to add try-run, cc-option and .DELETE_ON_ERROR to tools/build/Build.include?

To be safe, I just copy-pasted what the makefiles need. If someone wants to refactor the tool build system, that is fine, but, to me, I do not see consistent rules or policy under tools/.

"Please put this in a common file instead of introducing duplication" is not asking for wholesale refactoring. Paolo

Kbuild and the tools are divorced. They cannot be married unless the tools/ build system is largely refactored. That will be a tons of works (and I am not sure if it is welcome). The Kbuild refactoring should not be bothered by the tools. For now, I want them separated from each other. -- Best Regards Masahiro Yamada

Since commit d9f4ff50d2aa ("kbuild: spilt cc-option and friends to scripts/Makefile.compiler"), some kselftests fail to build. The tools/ directory opted out Kbuild, and went in a different direction. They copy any kind of files to the tools/ directory in order to do whatever they want to do in their world. tools/build/Build.include mimics scripts/Kbuild.include, but some tool Makefiles included the Kbuild one to import a feature that is missing in tools/build/Build.include: - Commit ec04aa3ae87b ("tools/thermal: tmon: use "-fstack-protector" only if supported") included scripts/Kbuild.include from tools/thermal/tmon/Makefile to import the cc-option macro. - Commit c2390f16fc5b ("selftests: kvm: fix for compilers that do not support -no-pie") included scripts/Kbuild.include from tools/testing/selftests/kvm/Makefile to import the try-run macro. - Commit 9cae4ace80ef ("selftests/bpf: do not ignore clang failures") included scripts/Kbuild.include from tools/testing/selftests/bpf/Makefile to import the .DELETE_ON_ERROR target. - Commit 0695f8bca93e ("selftests/powerpc: Handle Makefile for unrecognized option") included scripts/Kbuild.include from tools/testing/selftests/powerpc/pmu/ebb/Makefile to import the try-run macro. Copy what they want there, and stop including scripts/Kbuild.include from the tool Makefiles.
