Change the default behaviour of the PE targeted linker so that timestamps are
inserted. This is for compatibility with other, non-GNU tools. Deterministic
binaries can still be created by using the new --no-insert-timestamp command line
option.
* emultempl/pe.em: Initialise insert_timestamp to true.
Add a --no-insert-timestamp command line option.
* emultempl/pep.em: Likewise.
* ld.texinfo: Document that --insert-timestamp is enabled by
default and that it now has an inverse command line option.
* NEWS: Mention the new behaviour.
