fpu: Always decide no_signaling_nans() at runtime

Browse source 
Currently we have a compile-time shortcut where we
return false from no_signaling_nans() on everything except
Xtensa, because we know that's the only target that
might ever set status->no_signaling_nans.

Remove the ifdef, so we always look at the status flag;
this has no behavioural change, but will be necessary
if we want to build softfloat once for all targets.
