resolved fdo#58503 restore awkward handling of empty locale for legacy

Partly reverts d7a5ec62e91ce3dc5b784815254218f16181f676

An empty locale was treated as LANGUAGE_NONE, effectively being
interpreted as absence or undetermined or multiple or all depending on
context. Restore this behavior as it was an undocumented feature of the
API.
