rtti.c: honor-std + new-abi: __vmi_class_type_info not in std::

[Alfred Minarik]

I could not resist trying the new new-abi and failed quite at the first link: 

While in the runtime libgcc.a (tinfo.h) 
class __vmi_class_type_info is declared in std:: ,
this seems to be missed in rtti.c
resulting in a linktime error.

Example:
[ compiler build with -fhonor-std -fnew-abi 
[ gcc version 2.96 20000224 (experimental) 
[ i686-pc-linux-gnu

---bug.cpp---
struct A {};

struct B {
  virtual ~B(){}
};

struct C: A, B {};

main() {
  return 0;
}
---
>gcc bug.cpp -fhonor-std -fnew-abi
/tmp/ccXdTKMb.o(.gnu.linkonce.d.__ti1C+0x0): undefined reference to `__vmi_class_type_info virtual table'
collect2: ld returned 1 exit status
---

Analogous to other uses in rtti.c 
the following seems to fix it.
