selftests: allow detection of build failures
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.
