do not throw enable_tool_name_check error when compiling for Android and iOS
This check only fails when building for Android and iOS, it does not do something useful there. So when compiling for Android or iOS, it should be disabled by default. Or perhaps even better: it should only be enabled on platforms where it is useful. The Guardian Project, Thali, and Briar Android builds have always used --disable-name-tool-check. The iCepa Tor.framework also does.
