Trying to reproduce a releng auto cluster build of netbsd-8
locally fails to create the same results. There are binary
difference in the debug sections. Two random examples:

All differences I looked at are exactly like this, and always only a single
line of differences early at the start of the hexdump.

I believe this is the checksum. So this means that the debug files
must be different. Have you compared the debug sets?
