Bug Description
[Impact]
The kernel crashes when building coreutils on arm64, impacting the Ubuntu buildds. Also maybe considered a local DoS, as it can be used by a local non-privileged user to crash a system.
[Test Case]
Build the Ubuntu coreutils package w/ tests enabled (the default) on an arm64 system.
[Regression Risk]
I'm no expert in this code, but it is an obviously missing part of the backport, and looks identical to what was used in other upstream stable trees (3.12.y in particular). So, though I don't feel like I can properly assess the regression risk - at least we should have some interest from upstream to help fix regressions that do pop up.

For what it's worth, coreutils has never been built on a 3.13 distro kernel before, the last successful builds were all on the APM 3.8.0-2-mustang (or earlier) kernels.
