The prebuilt sysroot was from Ubuntu distribution. We did not build them from source. If you had downloaded the https://launchpad.net/linaro-toolchain-binaries/trunk/2012.03/+download/crosstool-ng-linaro-1.13.1-2012.03-20120326.tar.bz2, please try the scripts: contrib/linaro/make-sysroot.sh > Please note that I'm not asking in general how to build glibc.

The source tarball is http://releases.linaro.org/13.10/components/toolchain/eglibc-linaro/eglibc-linaro-2.18-2013.10.tar.bz2 It is built by http://releases.linaro.org/13.10/components/toolchain/binaries/crosstool-ng-linaro-1.13.1-4.8-2013.10.tar.bz2. Please refer the aarch64-linux-gnu config at crosstool-ng-linaro-1.13.1-4.8-2013.10/samples/linaro-aarch64-linux-gnu/crosstool.config. If you can contribute your patch back to glibc/eglibc upstream, that will be great.
