configure: Report unknown target names more helpfully
If the user specifies a target list themselves, check each entry to make sure it's a target we recognise. This allows us to print a helpful error message, rather than falling through (where we would probably eventually end up hitting the uninformative "ERROR: Unsupported target CPU").
