* ldmain.c (main): Make config.magic_demand_paged be true

	* ldmain.c (main): Make config.magic_demand_paged be true
	by default.  Don't the WP_TEXT and D_PAGED flags of
	output_bfd here; it's too late, so set it when output_bfd
	is created (in ldlang.c).  Also fix setting of EXEC_P flag
	* ldlang.c (ldlang_open_output):  Set output_bfd->flags here.
	* ldlang.c: Remove some duplicate extern declarations.
	* ldgram.y: Fixes to -N and -n options.
	* Makefile.in:  Recognize upper case letters in sed script
	to remove assignments from script files.
	* ldtemplate:  Don't assukme that -N or -n options
	imply use of -r script.
	* mkscript.c:  Tweaking to correctly handle \n and \\ in input.
