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").
