Use the solution described in [1] to provide a wrapper to the 'date' command that uses SOURCE_DATE_EPOCH if available. This is needed for reproducible builds. The -d "@..." syntax was introduced in GNU date about 2005 (but only added to the docuemntation in 2011), so I assume a version supporting this syntax is available, if SOURCE_DATE_EPOCH is defined. If SOURCE_DATE_EPOCH is not defined, nothing changes with respect to the current behavior. Update all users of 'date' in the tree to use the new wrapper.
