re PR testsuite/36057 (struct-layout-1_generate.c uses non-ISO C '%n$' operand number formats)

	PR testsuite/36057
	* g++.dg/compat/struct-layout-1_generate.c (DG_OPTIONS): Remove.
	(const char *dg_options): New array.
	(switchfiles): Loop through dg_options array to generate dg-options
	directives.  Remove numbered arguments usage from fprintf
	format strings.
