Details:

In tests rdiff-backup does on source and target directories it should also
check whether Python lstat function returns 64 bit or 32 bit (signed!) values
for file sizes.

The problem is that if Python on a target system has been compiled without
large file support backup of > 2 GB files always fail with "Updated mirror
temp file does not match source" as source and target file sizes differ
(because of an integer overflow).

I believe rdiff-backup should detect this in advance and at least issue a
meaningful warning because it is hard to understand what is the problem from
"Updated mirror temp file does not match source" message in this case. (And
maybe skip backuping > 2 GB files altogether.)
