Fix git-pack-objects for 64-bit platforms
The offset of an object in the pack is recorded as a 4-byte integer in the index file. When reading the offset from the mmap'ed index in prepare_pack_revindex(), the address is dereferenced as a long*. This works fine as long as the long type is four bytes wide. On NetBSD/sparc64, however, a long is 8 bytes wide and so dereferencing the offset produces garbage.
