[Bug ld/11434] New: ld resolves relocations against STB_GNU_UNIQUE in DT_SYMBOLIC libraries

[jakub at redhat dot com]

int i;
static int * g(void)
{
  return &i;
}
struct S {
  static int * f(void)
  {
    static int *p = g();
    return p;
  }
};

int * wrap2_f (void)
{
  return S::f();
}

g++ -O2 -fpic -shared -o lib.so lib.cc -Wl,-Bsymbolic
(assuming gcc has been configured to use STB_GNU_UNIQUE).
There are no relocations against _ZZN1S1fEvE1p (STB_GNU_UNIQUE) symbol defined
in this library.  While for non-STB_GNU_UNIQUE symbols that's desirable, the
symbol will always resolve to the containing library, for STB_GNU_UNIQUE it
causes the symbol to be no longer unique in the whole program.
