Though Android OSs are based on Linux, they have very unique APIs that desktop OSs do not have.
e.g. Bonic C lib, /dev/binder, libandroid.so, lots of Java native APIs, etc.
Plus, Android has own different directory structures, environment variables, application starting scheme and security.
I think it seems better choise to distinguish mobile platforms from desktop OSs.

Build a Version the right way in Strip module

per @23Skidoo's suggestion in #2356

Quiet version checking for `strip`

Fixes #2359.

Since the version checking code for `strip` on many platforms will fail
without consequence, we don't want to warn every time it does.

Fixes #2339
