Bug#1030159: dpkg: Please add future:+time64 option for y2038 support on 32-bit platforms)

[Helge Deller]

Just for the record:
The "tar" package is one example needs LFS- and 64-bit time support to 
sucessfully
run the built-in testcase and as such would be a good user for a new 
"future:+time64"
flag. See:
