I won't repeat the patch body, but I had to write a log message, so 
here is what I tentatively committed (not queued yet).

Subject: archive-tar: huge offset and future timestamps would not work on 32-bit

As we are not yet moving everything to size_t but still using ulong
internally when talking about the size of object, platforms with
32-bit long will not be able to produce tar archive with 4GB+ file,
and cannot grok 077777777777UL as a constant.  Disable the extended
header feature and do not test it on them.
