From 76ad07a4938aac69cb12bfdf52c3bf612c85e4df Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Mon, 8 Apr 2013 12:11:26 +0100 Subject: [PATCH] configure: Provide and use convenience error reporting function Provide a convenience function for reporting an error and exiting, and update various places in the configure script to use it. This allows us to be a little more consistent about how format our error messages and makes the calling code shorter.
