version v1.4.6-jp-4

[Android] Added as default to add Google Play Games Services Library. See README-dev for more details.
The only difference between if and else case seems to be the following lines only:
$(REGION)/libs/google-play-services.jar:
+	cp -p $(GOOGLE_SDK_PATH) $(REGION)/libs/

Can't we do it like this?

ifeq ($(GOOGLEPLAY),1)
$(REGION)/libs/google-play-services.jar:
	cp -p $(GOOGLE_SDK_PATH) $(REGION)/libs/
endif
