libstdc++: std::stoi etc. do not need C99 <stdlib.h> support

Dave, does this patch work for hppa64-hp-hpux11.11 ?

It should allow you to compile + run the code below:

#include <string>
int main()
{
  std::string z =3D "0";
  return std::stoi(z) + std::stol(z) + std::stoul(z) + std::stoll(z)
    + std::stoull(z) + std::stod(z);
}

I'm not sure if double and long double are the same representation on this
target, but if they are then std::stold("0.0") should work too.=
