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.

-Insert a real timestamp into the image, rather than the default value
-of zero.  This will result in a slightly different results with each

+@itemx --no-insert-timestamp
+Insert a real timestamp into the image.  This is the default behaviour
+as it matches legacy code and it means that the image will work with
+other, proprietary tools.  The problem with this default is that it
+will result in slightly different images being produced each tiem the
+same sources are linked.  The option @option{--no-insert-timestamp}
+can be used to insert a zero value for the timestamp, this ensuring
+that binaries produced from indentical sources will compare
+identically.
