附上安装步骤：
#mkdir /home/glibc_bulid
#mv glibc-2.20.tar.bz2 ./glibc_bulid
#mv glibc-linuxthreads-2.5.tar.bz2 ./glibc_bulid
#cd glibc_bulid

解压
#tar -jxvf glibc-2.20.tar.bz2
#cd glibc-2.20
#tar -jxvf ../glibc-linuxthreads-2.5.tar.bz2
#cd ..
#export CFLAGS="-g -O2 -march=i486"
#./glibc-2.11/configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin
#make
#make install
配置那步出现问题！请大神帮忙！
