From b9ca4ba9c9f4d536bda98932a149095af6115dad Mon Sep 17 00:00:00 2001
From: Joel Sherrill <joel.sherrill@OARcorp.com>
Date: Mon, 1 Dec 1997 17:07:52 +0000
Subject: Even more cleanup to make sure all the --enable/disable options avoid
 generating Makefiles where possible.

Added code to make sure make/custom file and bsp directory exist for
configured bsps.  This code also accounts for "aliased" BSPs.
