   We ship our own compiler support libraries to ensure a minimum level of
   support for BB-built libraries, however certain distros provide very
   bleeding-edge compilers.  This can be a problem if we download an
   _older_ `libstdc++.so` and forcibly link against that when launching
   Julia, as when Julia itself is built with the local `g++`, it may use
   symbols that don't exist in the BB-sourced `libstdc++.so`.
   
   To address this, we default to not using BB-sourced CSLs if the
   `libstdc++.so` that the native compiler would use contains a symbol that
   our BB-sourced CSLs do not have.  We use the monotonically-climbing
   `GLIBCXX_3.4.XX` version symbols for this purpose; encoding the "next"
   version number within `deps/csl.mk`, and triggering the BB-avoidance if
   that version exists within the system-provided `libstdc++.so`.
