From 25b483381adf4144bad3cf3f433b4658da5e15bb Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Mon, 20 May 2013 16:16:16 +0100 Subject: [PATCH] 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").
