交叉编译glibc-2.9时出现如下错误提示：

mawk: scripts/gen-sorted.awk: line 19: syntax error at or near ]
mawk: scripts/gen-sorted.awk: line 19: runaway regular expression /, "", subd ...

引用如下：

首先将debian系统中的awk由mawk变为gawk,这是由于两者在处理上有些语法差别:
apt-get install gawk
mv /usr/bin/{mawk,mawk.orig}
cp /usr/bin/{gawk,mawk}

解决二（来自网络）：

http://sourceware.org/ml/crossgcc/2007-07/msg00029.html

此方案在后续使用mawk编译时仍会碰到问题。

引用如下：

This is a simple patch when you still want to be using mawk.
Check the line numbers, did it for 2.6 and not 2.5
