fatal: bad config line 1 in file .git/config

1. 出现的第一个错误，可能是因为git代码是从别人的电脑和账号拷贝过来的

fatal: bad config line 1 in file .git/config

2. 出现的第二个错误，删除原来的git数据，重新整了一份就出现这个错误。

fatal: bad revision 'HEAD'

3. 以上两个的解决办法是，重新配置一下git即可

git config --global user.name "qiaohaiquan90"

git config --global user.email "qhq@lierda.com"
git init

4. 下一个问题，说是这个文件太小了，百度说是软链接消失了

/lib/gcc/arm-none-eabi/7.2.1/liblto_plugin.so: file too short
collect2: error: ld returned 1 exit status

进入文件目录看下是否真的不见了软链接，似乎确实不见了，那么需要重新建立软链接

重新建立软链接，问题解决。
