Bug 969164 - Replace most BUILDING_JS uses with JS_STANDALONE. r=gps Before making top-level traverse js/src moz.build files, there was a need to distinguish between top-level traversing e.g. top-level moz.build or config/moz.build and js/src traversing them. With a single traversal of both moz.build sets, we now only need to distinguish between js standalone builds and gecko builds. There is still, however, a need to distinguish between top-level vs. js/src configure runs on gecko builds to make them subconfigure icu and libffi from top-level instead of js/src in js standalone builds, or when choosing to make js/src's config.status do something when run or not.
