there is a certain amount of unwelcome duplication in the darwin  
LINK_COMMAND_SPECs.
this splits the LINK_COMMAND_SPECs into two parts and only changes the  
bit that's necessary for darwin >= 9

successful bootstraps on {powerpc*,i686}-apple-darwin9, i686-apple- 
darwin8, x86_64-apple-darwin10.

OK for trunk?
Iain

gcc/

	* config/darwin.h (LINK_COMMAND_SPEC): Split into...
	(LINK_COMMAND_SPEC_A): New.
	(DSYMUTIL): New.
	(DSYMUTIL_SPEC): New.
	* config/darwin9.h (LINK_COMMAND_SPEC): Remove.
	(DSYMUTIL_SPEC): Update for darwin >= 9 requirements.
