zig: fix compilation on Darwin AArch64

[strager]

On macOS AArch64, Zig's zig0 build is failing with the following error:

Undefined symbols for architecture arm64:
  "operator delete[](void*)", referenced from:
      lld::elf::Configuration::~Configuration() in liblldELF.a(Driver.cpp.o)
      ...
  "operator delete(void*)", referenced from:
      _ZigLLVMGetNativeFeatures in libzigcpp.a(zig_llvm.cpp.o)
      ...
  "operator new[](unsigned long)", referenced from:

      ...

      ...

      ...
ld: symbol(s) not found for architecture arm64
clang-13: error: linker command failed with exit code 1 (use -v to see invocation)

This is because libc++ is selected during linking, but the libc++abi
isn't linked. Link libc++abi to fix the errors.

I think macOS x86_64 is still failing for a different reason.

Description of changes

HELP: Do I need to document somewhere that libc++abi was added to all libc++-using builds? This patch affects more than just the zig package.

zig is now building on aarch64-darwin so I'm closing this in favour of #181485, thanks anyway for the PR.
