[Bug 1711478] Re: [FTBFS] arm does not define __NR_migrate_pages

[dann frazier]

This is now fixed in upstream, and I've prepared an NMU to sid to fix it
in Debian. This should therefore automatically be fixed after the first
debian sync for 18.10.

** Changed in: numactl (Ubuntu)
       Status: Invalid => In Progress

Title:
  [FTBFS] arm does not define __NR_migrate_pages

Status in numactl package in Ubuntu:
  In Progress
Status in numactl package in Debian:
  Confirmed

Bug description:
  numactl currently FTBFS since arm does not define __NR_migrate_pages.

  As described in the Debian bug comments [1] the function should just
  return -1 and set errno when __NR_migrate_pages is undefined. This
  prevents it from failing the build.

  
  Failure from the buildlog [2]:
