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