Hi Richard,

I've replicated your PR to make the objective-c checksum compare equal

commit fb2647aaf55b453b37badfd40c14c59486a74584
Author: Richard Biener <rguenther@suse.de>
Date:   Tue May 3 08:14:27 2016 +0000

    Make-lang.in (cc1-checksum.c): For stage-final re-use the checksum from the previous stage.
    
    2016-05-03  Richard Biener  <rguenther@suse.de>
    
    	c/
    	* Make-lang.in (cc1-checksum.c): For stage-final re-use
    	the checksum from the previous stage.
    
    	cp/
    	* Make-lang.in (cc1plus-checksum.c): For stage-final re-use
    	the checksum from the previous stage.
    
    From-SVN: r235804


This silences the stage compare.

Bootstrapped and reg-tested on x86_64-pc-linux-gnu.
Is it OK for trunk?


Thanks
Bernd.

This breaks bootstrap2.

Sorry for the breakage,

I've committed the following as obvious after
confirming that it fixes bootstrap2:

Subject: [PATCH] Fix bootstrap2 breakage due to re-use of obj-c checksum

gcc/objc:

	stage checksum exists.
