Centos 5.3 does not supports Glibc 2.7

Centos 5.3 does not supports Glibc 2.7. But nios2-linux-20090928.tar requires for it.

I could not find one soulution by google. It is said we could not use new version of Glibc for CentOS5.3 because Glibc is very important.

I edit 'config.arch' file and reivse the tool chain to old 'nios2-wrs-linux-gnu'. But it still has problem.

Following is the error report for nios2-linux-20090928.tar.

chmod +x tools/romfs-inst.sh tools/modules-alias.sh tools/build-udev-perms.sh

. linux-2.6.x/.config; if [ "$CONFIG_INITRAMFS_SOURCE" != "" ]; then

mkdir -p `dirname $CONFIG_INITRAMFS_SOURCE`;

touch $CONFIG_INITRAMFS_SOURCE || exit 1;
