Git master as of that point. Revision 46cf540e63a848512617b20fd8492f81bfb2f704
There was a problem that we had with file at one point and thought was fixed. If you check in your tmp/sysroots directory for the host machine, do you have a file.real?
I do have a tmp/sysroots/x86_64-linux/usr/bin/file.real -- although I'm building for BeagleBoard, and don't have one in that directory.
