fix(3p): resolve linker issues with clang-compiled C++ packages The point where this broke is likely when llvmPackages_11.stdenv started respecting stdenv.hostPlatform.linker and thus using GNU binutils' ld.bfd for linking. That linker can't deal with clang's C++ ABI. To fix this we introduce a modified version of llvmPackages_11.stdenv which uses llvmPackages_11.bintools for linking purposes (I also aim to upstream this in some form, but am not sure about the details atm, so we'll just do this in the tvl overlay for now). This is the precondition for getting our C++ packages in //third_party to work again. Additionally the following fixes were necessary: * abseil-cpp needed to be updated (by overriding the version from nixpkgs for now, since I can't update the subtree on my own) to fulfill grpc's requirements (grpc 1.41.0 needs abseil-cpp LTS 20210324). * gtest needs a patch from nixpkgs which fixes the path to its include directory for CMake. * We need to build re2 with clang as well, otherwise linking will fail. Fixes b/132.

chore(3p): bump NixOS channels to 2021-11-03 * //third_party/{abseil_cpp, grpc}: fix linker problem by passing the C++ standard to use explicitly. nixpkgs upstream stopped passing this to abseil between bumps and the way this problem manifests itself is linker errors, because… C++, I suppose.
