Alan Modra 5c3049d2ef * ld.texinfo (Expression Section): Describe treatment of numbers
and absolute symbols.
	* ldemul.c (after_open_default): Look up __ld_compatibility.
	* ldexp.c (fold_name): Convert absolute symbols to numbers when
	inside output section definitions, or when __ld_compatibility >= 221.
	(exp_fold_tree_1): Convert numbers to absolute when not in output
	section definition and __ld_compatibility < 221.  Don't always
	convert values outside an output section definition to absolute.
	* ldexp.h (uses_defined): Comment.
	* ldlang.c (ld_compatibility): New variable.
	* ldlang.h (ld_compatibility): Declare.
