* windres.c (define_resource): Use zero for timestamp, making
output deterministic. time.h include is no longer needed.
* resres.c (res_append_resource): Likewise.
* pe-dll.c (fill_edata): Only use a real timestamp if
--insert-timestamp was used.
* emultempl/pe.em: Add the --insert-timestamp option.
* emultempl/pep.em: Likewise for 64bit.
* ld.texinfo: Document the --insert-timestamp option.
* libcoff-in.h: Add insert_timestamp flag to the pe_data struct.
* libcoff.h: Regenerate.
* peXXigen.c (_bfd_XXi_only_swap_filehdr_out): Only use a real
timestamp if --insert-timestamp was used.
