Do we need to mention binutils in the required build dependencies? It's kind of implicit though since also ld is in binutils

Can't hurt to list the requirement explicitly, right?

… new 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`.
