[Bug target/25477] New: __builtin_sqrtl/__builtin_printf does not work unless including math.h/stdio.h

["pinskia at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The following program does not work if we don't include math.h and stdio.h.

long double f(long double a)
{
  return __builtin_sqrtl (a);
}

int main(void)
{
  __builtin_printf("%Lf %f\n", f(2.0) + 2, 200.0);
}

The fortran failure gfortran.dg/large_real_kind_2.F90 is the same issue.

Note __builtin_printf is wrong even when including stdio.h
