Hum. There are a few tests, that are supposed to detect systems that
don't support that test, like systems with noatime filesystems and skip
that particular test.

In particular for noatime:

  elif test -f /etc/mtab && { grep $(df . 2>/dev/null| tail -n1 | awk '{print $1}') /etc/mtab | grep -q noatime; }; then

...which doesn't catch the problem in the buildd, it would seem.

It does work on my laptop, but then, I have no clue about buildds. :)

Someone with a better, more portable version of that test around?
