Yep, it can do. Look at the example given at the end of:

http://www.gnu.org/software/make/manual/make.html#Prerequisite-Types

```
$(OBJS): | $(OBJDIR)

$(OBJDIR):
mkdir $(OBJDIR)
```

This is saying the the objects should be made after their containing directory is made. Both the objects, and the directory that conatains the objects are made by Make. The order only dependancies is used to hint Make in which order it should do these.

How is this applicable to your use case here?

To put it another way, what happens if you don't specify this dependency? Does anything break?

If it nothing breaks, why are you using it?
