Fix some symbol version mismatches between libstdc++ and libsupc++/libcxxrt

that were causing the runtime and STL libraries to see different versions of
various classes and functions when libstdc++ is used as a filter.

Note: This changes the ABI for libcxxrt, but libcxxrt is currently only in
-STABLE for testing and is not used by anything unless explicitly enabled by
the end user.  No default compiler configurations use it.

libc++ will need to be recompiled after this change.  make buildworld will do
this automatically, but make in lib/libc++ will not necessarily work unless the
new libcxxrt is installed first.
