我正在尝试使用构建工具链crosstool-ng，我已经全部设置好，按照http://crosstool-ng.org/#download_and_usage中的描述选择了我的 cpu ，我正处于可以构建工具链的步骤. 但是，当我输入ct-ng build时，它会因以下错误而取消：

我知道它无法检索内核，有没有办法可以手动下载它并告诉脚本 tarball 的位置？
好的，我意识到这
wget http://www.kernel.org/pub/linux/kernel/v4.x/linux-4.3.tar.gz会失败，但wget --no-check-certificate http://www.kernel.org/pub/linux/kernel/v4.x/linux-4.3.tar.gz可以通过代理很好地下载 tarball。所以我复制/usr/bin/wget到 /usr/binwget~orig and wrote a wrapper/usr/bin/wget`，看起来像：
#!/bin/bash
/usr/bin/wget~orig --no-check-certificate $1
但这似乎也不起作用，我现在得到以下内容build.log：
[DEBUG] ==> Executing: 'wget' '--passive-ftp' '--tries=3' '-nc' '--progress=dot:binary' '-T' '10' '-O' '/home/ron/src/toolchain/work/.build/tarballs/linux-4.3.tar.xz.tmp-dl' 'http://www.kernel.org/pub/linux/kernel/v4.x/linux-4.3.tar.xz'

它如何自动知道我的原始wget二进制文件现在被称为wget~orig??? Andit 尝试使用它而不是我现在位于的包装器/usr/bin/wget（是的，我已经添加了 x 权限并尝试了它，wget http://www.kernel.org/pub/linux/kernel/v4.x/linux-4.3.tar.gz来自 shell 的一个（使用我的包装器脚本）现在工作得很好......
