commit 5fda82641461a5234ab9bf0575423dfb8bfc5657 Author: Jan Beulich <jbeulich@xxxxxxxx> AuthorDate: Tue Feb 27 13:57:31 2024 +0100 Commit: Jan Beulich <jbeulich@xxxxxxxx> CommitDate: Tue Feb 27 13:57:31 2024 +0100 build: make sure build fails when running kconfig fails Because of using "-include", failure to (re)build auto.conf (with auto.conf.cmd produced as a secondary target) won't stop make from continuing the build. Arrange for it being possible to drop the - from Rules.mk, requiring that the include be skipped for tools-only targets. Note that relying on the inclusion in those cases wouldn't be correct anyway, as it might be a stale file (yet to be rebuilt) which would be included, while during initial build, the file would be absent altogether.
