* defs.h: Define TARGET_{FLOAT DOUBLE LONG_DOUBLE}_FORMAT

Browse Source 
defaults for bi-endian targets.  Replace function pointers for
	floatformat routines with macros.  No need for these to be runtime
	selectable.
	* findvar.c:  Get rid of floatformat function pointers.  Use
	macros in extract_floating and store_floating.
	* remote-nindy.c (nindy_fetch_registers nindy_store_registers):
	Use floatformat macros.
