[Bug target/20228] New: [4.1 Regressions] Cannot link two valid C++ TU together

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

Try linking the following two C++ sources together:
struct a
{
  virtual void g();
  virtual void f(){}
};
int main() { a b; b.f(); b.g(); }
---- cut -----
struct a
{
  virtual void g();
  virtual void f(){}
};
void a::g() {}

We get an error:
/tmp/ccFSWYxL.o(.eh_frame+0x11): undefined reference to `__gxx_personality_v0'
/tmp/ccUWWgfl.o(.gnu.linkonce.r._ZTI1a[typeinfo for a]+0x0): undefined reference to `vtable for 
__cxxabiv1::__class_type_info'
This is relative new binutils too:
GNU ld version 2.15.94 20041104

Also this breaks building libjava on the same target.
