+Subject: [PATCH] cross
+
+We need to be able to trigger configure's cross code but we don't want
+to set cross_prefix as it does other things we don't want. Patch things
+so we can do what we need in the target config case.
+
+Upstream-Status: Inappropriate [may be rewritten in a way upstream may accept?]
