Bug description:
  syscall.Getpagesize returns wrong page size on aarch64.

  The code at https://github.com/vielmetti/go-pagesize-test exercises
  the issue.

  This is fixed upstream at 1.8 with
  https://github.com/golang/go/commit/1b9499b06989d2831e5b156161d6c07642926ee1

  Downstream, this affects Docker and Kubernetes on aarch64,
  specifically at

  https://github.com/docker/docker/issues/27384 for Docker (overlay2
  filesystem).

  Please consider a backport of the page size fix to 1.6 version of Go
  that is part of 16.04 LTS.

  thanks

  Ed

  What I expected to happen:

  C.getpagesize()) and syscall.Getpagesize() return the same value

  What happened instead:

  On aarch64,

  ✗ go reports correct pagesize
     (in test file go-pagesize-test.bats, line 3)
       `[ "$status" -eq 0 ]' failed
       OS page size = 4096 ; go reports 65536
