From a00164efc94da6953c78f59b2053b3af20fa16df Mon Sep 17 00:00:00 2001
From: P. J. McDermott <pjm@nac.net>
Date: Sat, 10 Nov 2012 00:08:15 -0500
Subject: Update build makefile (mostly "install" target).

  * Read target architectures from generated configuration file.
  * Use new features of opkhelper (i.e. oh-autoinstall).
  * Remove libiberty.a.
  * Remove hard links to tools (in TOOLBINDIR).
  * Put ldscripts where we want them in a decent way.
  * Put BFD and opcodes libraries and headers where we want them in a
    decent way.
  * Fix creation of ld.so.conf.d.
  * Give ld.so conf files names that are specific to host architectures.
  * Run oh-fixperms.
