Patch for gcc_release

[Joseph S. Myers]

The 3.3 snapshot run just failed
<http://gcc.gnu.org/ml/gccadmin/2004-q2/msg00093.html> because an upgraded
version of diff (I assume) rejected the -3 option.  This option never did
more than confirm a default, so can safely be omitted.  I'll apply this
patch to mainline when unfrozen (it should perhaps go on release branches
as well; branch release scripts are used to run releases from those
branches and it would save surprises if the RMs happen to upgrade diff).

(Paul Eggert did submit a patch for this two years ago, but any question
of fixing those scripts that _can_ assume POSIX or indeed GNU utilities to
work with the strict POSIX-2001 modes has always been lost up in the
general discussions of the brokenness of those modes and the need to
support pre-POSIX-1992 systems.  
<http://gcc.gnu.org/ml/gcc-bugs/2002-02/msg00540.html>.)

	* gcc_release (DIFF): Remove -3 option.
