Bug description:
  [Impact]

   * grub2 builds freestanding libc-less minilzo library to be used by the bootloader code.
   * It has a vendorized copy of it, whilst the distribution has newer copies of it.
   * Specifically distribution build has FTBFS fixes for new compiler and CVE fixes, specifically https://ubuntu.com/security/cve-2014-4607

  CVE-2014-4607

   * Building grub with minilzo from the archive seems to be the best
  way to keep minilzo up to date and secure

  [Test Case]

   * Check that grub can open lzo compressed files in the command line
  prompt, for example by having /boot on btrfs filesystem with
  compress=lzo option.

  [Where problems could occur]

   * Changes limited to lzo compression, so for example grub may fail to
  mount / read data off btrfs filesystem with compress=lzo

  [Other Info]

  Fixed in:

  hirsute grub2 2.04-1ubuntu37
  hirsute grub2-signed 1.157
