 Running on Ubuntu 14.04.1 I am trying to build a stage1 cross-compiler for
 a Raspberry Pi running Raspbian.  I am using the tool chain located at
 https://github.com/raspberrypi/tools.

 I copied my Raspberry Pi's /include and /usr directories to my build
 machine into directory `/home/johnma/rpi-toolchain/rootfs`.

 Following these instructions [https://ghcarm.wordpress.com/2014/01/18
 /unregisterised-ghc-head-build-for-arm64-platform/] I force gcc to use my
 sysroot using this bash script:

 `/home/johnma/mygcc` contains:
 {{{
 #!/bin/bash
 arm-linux-gnueabihf-gcc --sysroot=/home/johnma/rpi-toolchain/rootfs $@
 }}}

 I used this configure command:

 {{{
 ./configure --target=arm-linux-gnueabihf --enable-unregisterised --with-
 gcc=/home/johnma/mygcc --with-nm=/usr/bin/nm
 }}}



 The build ends with:
