Do we want this change for RISC-V, to fix PR113578?

I haven't tested it on RISC-V, only on x86_64-linux (where it doesn't do
anything).

libstdc++-v3/ChangeLog:

        PR libstdc++/113578
        * include/std/ostream (operator<<(basic_ostream&, float)):
        Restore signbit after converting to double.
No strong opinion.     One could argue that the existence of a 
conditional like that inherently implies the generic code is dependent 
on specific processor behavior which probably is unwise.  But again, no 
strong opinion.
