Doc patch: automatically set the subtitle

["Ben Elliston" <bje at au1 dot ibm dot com>]

The following patch allows the documentation's revision date to be
kept up to date.  Currently, the last revision date is shown as May
1993.  I'd like to think we're revising the documentation more
frequently than that :-)

Okay for mainline?

2004-12-06  Ben Elliston  <bje@au.ibm.com>

	* doc/Makefile.am (config.texi): Emit a @set UPDATED command to
	config.texi whose value is the current month and year.
	* doc/Makefile.in: Rebuild.
	* doc/binutils.texi: Set the document subtitle to be the value of
	the Texinfo UPDATED variable (obtained from config.texi).
