- config.h was used as target even when it wasn't generated. This only worked because the 'dummy' target always triggers a full rebuild. It is however better to specify the exact target that is to be rebuilt do avoid confusion. - Explicitly mark 'dummy' as a 'phony' target. Signed-off-by: Egbert Eich <eich@suse.com>
