<pre>
    I get errors to the tune of this when I've configured LLVM with `-DLLVM_STATIC_LINK_CXX_STDLIB=Yes -DLLVM_ENABLE_LIBCXX=Yes`.

```
mold: error: undefined symbol: __cxa_guard_abort
>>> referenced by iostream.cpp
>>> /home/cjdb/opt/lib/x86_64-unknown-linux-gnu/libc++.a(iostream.cpp.o):(std::__1::ios_base::Init::Init())

```

It looks like libc++abi isn't being linked, because things work when I add `LDFLAGS="-L${HOME}/opt/lib -lc++abi"`.
