4byte is used only on some targets, what exact assembler directive is used
for 4byte unaligned data is heavily target dependent.

	* gcc.dg/debug/btf/btf-cvr-quals-1.c: Use dg-additional-options
	instead of multiple dg-options.
	* gcc.dg/debug/btf/btf-datasec-1.c: Likewise.  Accept all supported
	unaligned 4 byte assembler directives rather than assuming it must
	be .4byte.
