dm368 ipnc3.0环境搭建脚本

前言

　　为了方便其他人搭建dm368 ipnc3.0环境，我写了个脚本，执行脚本就可以自动搭建好环境了，绝对的傻瓜操作了，不过有一个地方让我很郁闷，那就是在用sed替换掉某段内容的时候(143行--156行)，替换的文本有很多行且里面某些行必须要tab开头(makefile要求，这里看不出，上传的问题)，在我写的时候发现我必须把替换的内容靠在最左边，如果我想放到右边写，替换后内容就会包含左边的那些空格。放在最左边导致一点也不美观了，谁有更好的方法可以告诉我哈，先谢谢了！ (注意：我的代码其实是有对齐的，放上来就全部都靠左了，看不出我上面说的sed的问题了，实际情况如下图：sed替换的内容放到了最左边， 但我想要把sed替换的内容的每行靠右些，与上面的对齐，不知道我描述清楚了没，呵呵。 还有，如果有人想用这个脚本的话，请自己再测试下，因为我怕上传导致某些tab啊空格啊变了，我不怎么写脚本，所以有些地方可能有更好的方法实现，希望大家提出来，一起学习下，谢谢！)

注： 内部有一些对特定文件的处理，主要是因为我的环境是fedora14，make的版本较高和我认为ipnc3.0原始文件里面有个别文件有些小bug及针对于我们自己的设备的一些小的修改。
