[PATCH] D26385: Define __ANDROID_API__ for all Android builds.

What if only `arm-linux-androideabi` (without a version) is specified? We should be falling back to the old behavior (don't defined `__ANDROID_API__`) when that happens since that's what every build system out there is going to be relying on.
