From 9b71149ed6b4d3192cf139701bf1cae7d26dca96 Mon Sep 17 00:00:00 2001
From: Niklas Hallqvist <niklas@cvs.openbsd.org>
Date: Fri, 28 Feb 1997 23:22:08 +0000
Subject: First stab at a target for making cross-development tools: try "make
 TARGET=machine cross-tools" and you should get a little hierarchy in
 /usr/cross/<machine>.  This is probably not in its final shape yet ;-)
