two portability fixes

[Jim Meyering]

The first is just to fix a failing test.
For mv/i-3, the output file, "out" is empty on FreeBSD 8.1
Also, (and this is telling), it seems that no one is testing
on non-linux kernels.  On the first one I tried, just before
I was planning to release, "make check" reported 30+ failing tests,
all having to do with the new copying code.
