We should consider if adding an argument above like { withLibgcc ? stdenv.isLinux && stdenv.isAarch64 && stdenv.cc.isGNU, ... }: is better than putting these conditions inline in the body of derivations. This could make overriding LLVM easier and I think its self-documenting to have code in the form of effect ? cause rather than if ${cause} then ${action} else null.

Since this is just an ugly workaround, I would prefer to keep this as ugly as possible. 😬
