Intermittent testsuite failure on (at least) amd64

[Adam Conrad]

Binary package hint: tar

tar occasionally fails the truncate test on (at least) amd64, as can be seen in the ubuntu-autotest logs at https://lists.ubuntu.com/archives/ubuntu-autotest/2008-April/018799.html ... Note that a retry of this build (on the same machine, in the same build environment) succeeded, so reproducing this probably relies on performing several looping builds (or looking at the test itself to determine why it might be racy or time-of-day dependant)

I'm marking this as low priority, since it's easily worked around by just reattempting the build, but it's still a bug, so should be filed until proven fixed.

Note that this is *not* bug #25084, so please don't dupe it at such. :)
