stdio: Fix printing 0.0
We were relying on FE_DIVBYZERO being turned off when printing
"%f", +-.0
Avoid the whole issue by looking at the sign-bit (in a rough
approximation).
Note that we do not handle gracefully:
printf ("\n%llf\n", -0.0);
printf ("\n%llf\n", 0.0);
nor %Lf for both when NOT cast to long double. Avoiding an FPE due to
broken numbers like these does not make sense to me.
