Check GetLocaleInfoEx() API availability.
* locale-info.c (main): Rename it to...
(query_locale_info): ...this; call it conditionally, from...
(main): ...a subsequent reimplementation of this, provided that...
[(dll = GetModuleHandle ("kernel32.dll"))]: ...first this, and then...
[GetProcAddress (dll, "GetLocaleInfoEx")]: ...this is non-NULL.
