libstdc++: Add unused attributes to shared_ptr functions
This avoids some warnings when building with -fno-rtti because the
function parameters are only used when RTTI is enabled.
libstdc++-v3/ChangeLog:
* include/bits/shared_ptr_base.h (__shared_ptr::_M_get_deleter):
Add unused attribute to parameter.
* src/c++11/shared_ptr.cc (_Sp_make_shared_tag::_S_eq):
Likewise.
