Some production builds (i.e. Safari Technology Preview) build onto of a base SDK which already has libraries like bmalloc present. Under some configurations, simply passing `-lbmalloc` to the linker will silently link against the old bmalloc, when we really want it to fail. Fixing this would make it easier for production builders to understand the dependencies between WebKit's projects.
