I am not sure about exact reason, but this may be related to two events:

1) Introducing --as-needed linker option by default in Arch (see this [1] Fedora article for 
explanation) - happend long time ago

2) Splitting GLU in separate package from Mesa - recent (compared to previous change)

In the past GLU was tightly integrated in Mesa and game developer probably didn't consider it 
separate dependency from libGL, worth explicitly linking to.
