Description of problem:
RHEL7 ships with g++ 4.8.x, which is able to compile this C++11 snippet:

 # rh.cpp
 struct K { void f(void) const &; };
 void K::f(void) const & {}

When this K::f function happens to be in a shared library and a -Wl,--version-script file is used,

 # rh.sym
 XYZ { global: extern "C++" { K::*; }; local: *; };

then K::f becomes hidden on RHEL7, because Someone At RedHat™ forgot to update binutils when they updated gcc. (Since binutils bundles libiberty that originates from gcc.)


Version-Release number of selected component (if applicable):
binutils-2.23.52.0.1


How reproducible:
$ g++ rh.cpp -std=gnu++11 -fPIC -shared -Wl,--version-script=rh.sym -o rh.so
$ nm rh.so | grep _Z

Actual results:
- 0000000000000618 t _ZNKR1K1fEv
- Unhappy user
- Programs trying to use rh.so fail at link stage:
  rh.so: undefined reference to `_ZNKR1K1fEv'

Expected results:
- 0000000000000618 T _ZNKR1K1fEv
- Content user
