制作工具链时，编译完eglibc后，原先/tools/bin目录下能正常使用的GCC无法使用了

echo

出错信息如下：

大哥啊，你的文章我都看了1个多月了，我每次按照你的方法做GCC和Eglibc总是出错，每次还出错不一样，编译eglibc时有elf问题，有语言问题等等，总之很多。做GCC时，按你的版本我编译实在是过不去，我都要崩溃了，我现在用CLFS、加上LFS、再加上你的文章一起参考，然后一个一个版本的尝试，像GCC我从，4.4.5一直试到4.3.2，其中的每个版本我都试过了（补丁更是试了N多的组合），恩补丁还试过张乐的gentoo龙芯项目的补丁，最后到4.3.2才成功。

这其中什么原因我实在是不知道。

我的宿主系统是我和一个朋友自己通过X86平台交叉编译的N32系统

得亏这个星球上还有google这个东西，要不然，我觉得我早就放弃了。
