Haiku fixes year 2038 bug

time_t now uses 64-bit on 64-bit systems. This fixes the year 2038 bug for 64-bit Haiku, so we can continue to run it after 2038. This breaks the ABI, so all the 64bit packages were rebuilt.As Michel points out in the comments, this means Haiku'll be good until 4 December 292277026596, about in time for the beta release.
