Explicit when using function_ptr Phoenix binder

From the errors:

base type ‘float (*)(float, float) noexcept’ fails to be a struct or class type
 struct functor_action : public FuncT {
        ^~~~~~~~~~~~~~
‘float (*)(float, float) noexcept’ is not a class, struct, or union type
     struct result { typedef typename FuncT::result_type type; };
                                                         ^~~~
type ‘float (*)(float, float) noexcept’ is not a direct base of
‘phoenix::functor_action<float (*)(float, float) noexcept>’
     :   FuncT(fptr_) {}
                    ^

it seems that GCC, at least the ones on my system, failed to deduce that
the binder meant to be used when trying to bind the C Std Math Library's
powf and fmodf functions is of course the function pointer one
(specifically the 2 args specialisation), and not the functor one.
