glibc 编译错误

1、undefined reference to `__stack_chk_guard'

http://www.linuxquestions.org/questions/linux-from-scratch-13/install-glibc-2-17-error-help-me-4175460557/
GCC doesn't detect stack protection correctly, which causes problems for the build of Glibc-2.18, so fix that by
issuing the following command
Fixed by this sed in the gcc source before the first pass of gcc:
> 
> sed -i '/k prot/agcc_cv_libc_provides_ssp=yes' gcc/configure



2、ubuntu 确保使用 bash shell
使用如下命令查看使用的SHELL是什么，
$readlink -f /bin/sh
/bin/bash

如果是dash 而不是 bash
需要将符号链接改为bash
$ sudo rm /bin/sh
$ sudo ln -s /bin/bash /bin sh

重新编译Glibc
