I had missed the obvious ...  that we gained a   
"darwin_asm_named_section" along with lto...

... this is not as neat as Richard's suggestion...
... but it is entirely local to darwin (and roughly the same amount of  
work
"is it dwarf debug? yes..  did we emit this section yet? if no ...  
then put a label" )

if Mike is OK with this... , it does the job.

OK for trunk?

gcc:

	* config/darwin.c (darwin_asm_named_section): Check for __DWARF  
sections.
	(darwin_asm_dwarf_section): New.
	(darwin_file_start): Remove code emitting dwarf section symbols.
