title: error when building the arm-none-eabi toolchain
body: <p><strong>FOREWORD</strong> : My build system is based on Ubuntu 14.04 LTS server edition</p>
  
  <p>I have bumped into a common issue while cross-compiling binutils for the <strong>arm-none-eabi</strong> toolchain.</p>
  
  <p>After downloading the sources from :</p>
  
  <p><a href="https://launchpad.net/gcc-arm-embedded/4.8/4.8-2014-q3-update/+download/gcc-arm-none-eabi-4_8-2014q3-20140805-src.tar.bz2" rel="nofollow">https://launchpad.net/gcc-arm-embedded/4.8/4.8-2014-q3-update/+download/gcc-arm-none-eabi-4_8-2014q3-20140805-src.tar.bz2</a></p>
  
  <p>I extracted the tarball and patched zlib with :</p>
  
  <pre><code>$ cd ./gcc-arm-none-eabi-4_8-2014q3-20140805/src
  $ find -name '*.tar.*' | xargs -I% tar -xf %
  $ cd zlib-1.2.5
  $ patch -p1 &lt;../zlib-1.2.5.patch
  $ cd ../../
  </code></pre>
  
  <p>according to the instructions of the bundled PDF guide. I then applied this <code>sed</code> patch : </p>
  
  <pre><code>sed -i -e 's/@colophon/@@colophon/' -e 's/doc@cygnus.com/doc@@cygnus.com/' bfd/doc/bfd.texinfo
  </code></pre>
  
  <p>and launched the <code>./build-prerequisites.sh --skip_mingw32</code> and <code>./build-toolchain.sh --skip_mingw32</code> scripts.</p>
  
  <p>Altough the <code>./build-prerequisites.sh --skip_mingw32</code> works fine, the toolchain script ends with an error in the binutils install procedure : </p>

  <p>I have also edited the second script by replacing the <code>make</code> calls with the <code>make MAKEFINFO=true</code> ones but I get this error...</p>
  
  <p>....any suggestions about it ? I have been googling around so far and found that these ones are common problems occuring when working with the Ubuntu distros, but I still can't find a solution.</p>
  
  <p>Thanks in advance, Arturo</p>
