We don't try very hard, but it's also not listed to be last in the makefile that drives the build dependencies. In fact, it's in the middle of the dependencies for libxul... so I doubt even trying to move it there is going to affect the outcome much... At this point, someone needs to look at how Make actually orders the things it builds. It also doesn't help that Make (or ninja, etc. for that matter) is not aware of how long each target is going to take to build. If it did, it could decide ahead of time that anything it needs to build that is not a dependency of libxul could be built while libxul links. It could also decide that things that take longer should go as early as possible so that they don't remain pegging only one CPU if they happen last before what depends on them.
