[Bug libc/14047] strtof gives spurious ERANGE errors

As I understand it, the point of this case is that if you'd enabled 
trapping on underflow exceptions, your trap handler would be called, but 
without trapping enabled, this case will not set the underflow flag for 
later testing of whether the flag is set.  But for all other cases of 
exceptions, the circumstances when a trap handler would be called when 
trapping is enabled are exactly the circumstances the flag would be set.
