Creating such objects (without using them for the UI) is supported under all platforms, so allow doing it. Note that this is only supported under Unix systems when locale_t and related functionality is available, but this should be the case just about everywhere by now. Add a test (or, rather, replace an existing test which was disabled by default) checking that we can now get locale information about any locale, not necessarily the currently used one.
