byte ordering was big or little endian depending upon the target.
Modern floating-point formats are naturally ordered; in this case
__VFP_FP__ will be defined, even if soft-float.
FIXME: long double support is broken for the ARM when __ARMEL__
is specified. New long double formats need to be added
to the long double conversion routines. */
