Delaying fills generation while ordering sections in gold.

[Sriraman Tallam]

Hi,

   I have attached a simple patch to delay fills generation for output
sections when input sections could be reordered using
--section-ordering-file flag.


	* output.cc (Output_section::add_input_section): Delay fill
	generation for section ordering.



Thanks,
-Sri.
