Title:
  Failed to build libhugetlbfs-2.20 from source on 4.4 / 3.13 Trusty
  ARM64

Status in ubuntu-kernel-tests:
  Fix Released
Status in linux package in Ubuntu:
  Fix Released

Bug description:
  It will fail to build libhugetlbfs verison 2.20 for SRU regression-
  test on 3.13 ARM64

  It's ok on 4.10 / 4.4 ARM64, but not 4.4.0-88.111~14.04.1 and
  3.13.0-126.175 ARM64

  Looks like it's failing with:
  LD64 (hugelink_rw test) obj64/linkhuge_rw
  /usr/bin/ld: final link failed: File truncated

  This is not a regression. As this issue has been seen before.
