Commit 5f70bde26a48 ("selftests: fix build behaviour on targets' failures") added a logic to track failure of builds of individual targets. However, it does exactly the opposite of what a distro kernel needs: we create a RPM package with a selected set of selftests and we need the build to fail if build of any of the targets fail.
Both use cases are valid. A distribution kernel is in control of what is included in the kernel and what is being built; any error needs to be flagged and acted upon. A CI system that tries to build as many tests as possible on the best effort basis is not really interested in a failure here and there.
Support both use cases by introducing a FORCE_TARGETS variable. It is switched off by default to make life for CI systems easier, distributions can easily switch it on while building their packages.
Fine for me. My concerns as you said were only for CI systems and the fact that the build was failing in a non-deterministic way depending on the outcome of the last built subsystem only: I hadn't considered the opposite needs of a package build system. Sorry for that.
