	* config/rs6000/rs6000.c (rs6000_emit_move): If we load or store a
	long double type, set the flags for noting the default long double
	type, even if we don't pass or return a long double type.

	* gcc.target/powerpc/gnuattr1.c: New test to make sure we set the
	appropriate .gnu_attribute for the long double type, if we use the
	long double type, but do not generate any calls.
	* gcc.target/powerpc/gnuattr2.c: Likewise.
	* gcc.target/powerpc/gnuattr3.c: Likewise.
