Similar hilariously long lists can be found on many web-connected devices, from BMWs to iPhones.
(Pages 3 to 6 are the interesting ones though -- it shows that a majority of these libraries/codebases apply to the brand new S-Class. And the most noteworthy inclusion is AOSP, i.e. Android.)
Entertainment and navigation systems in cars use Android lately. They normally use the base operating system and APIs while the UI is always heavily customized, so you might not recognize it, but it's of course very convenient instead of developing a full OS for your cars.
These are mostly used for diagnosing/debugging the newer head units. They rely on BT and standard networking. GCC is pretty standard for any embedded device, I would say.
