Fix build errors when used by the Android Emulator

In the Android Emulator, there are two main differences:
1) googletest is the shared version 1.8.0, instead of the later commit
   used by astc-codec (to get bazel support).
2) Unit tests are all linked together into one binary, so one function
   needs to be marked "static".
