Subject: Introduce build script for arm-none-eabi cross-compilations

This is a necessary step to use libosmocore-arm dep in OsmocomBB.

After this patch is submitted the "./contrib/jenkins.sh" line in
libosmocore jenkins jobs [1][2] needs to be replaced with:

  if [[ "$JOB_NAME" == *"arch=arm-none-eabi,label=linux_amd64_debian8"* ]]
  then
    ./contrib/jenkins-arm.sh
  else
    # (FreeBSD && debian8)_amd64 builds
    ./contrib/jenkins.sh
  fi

Furthermore, the "arch" matrix-build axis has to be created,
holding "arm-none-eabi" and "amd64". Following combination filter
is necessary to skip cross-compilations on FreeBSD buildslave:

  !(arch=="arm-none-eabi" && label=="FreeBSD_amd64")
