the user to affect how packages are built (BUILD_DEFS) and the effects that those variables have (BUILD_DEFS_EFFECTS). The latter variable has been introduced to clearly separate these two issues. While here, reduced the indentation of the directives a little bit. One visible change is that "make build-defs-message" will always show the message when called directly. Before, it had been shown only once, which makes debugging a bit more difficult.
