 For this tutorial, we will put the toolchain in '''{{{/arm}}}''' directory rather than the usual {{{/usr/local}}}. I prefer this approach since it's easier to manage (for example, to delete everything when things don't work or when we're finished with it, or to put it on portable drive to be carried to different system).
