<pre>Repro:
1. Download
<a href="https://drive.google.com/file/d/1Gjrg4bQCv3uD9Ucqt4ZtroHrz5v0iCJX/view?resourcekey=0-f53UMW57gtrPlSis2sTjKg">https://drive.google.com/file/d/1Gjrg4bQCv3uD9Ucqt4ZtroHrz5v0iCJX/view?resourcekey=0-f53UMW57gtrPlSis2sTjKg</a>
and unzip it
2. ~/src/llvm-project/out/gn/bin/ld64.lld.darwinnew @response.txt
3. ./base_unittests --gtest_filter='*Exception*'
on macOS 10.14+, that starts fine (the test fails, but that's issue 48389).
On macOS 10.13, it fails with:
```
dyld: Symbol not found: __objc_empty_cache
Referenced from: /b/s/w/ir/out/gnmac/./base_unittests
Expected in:
/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation
in /b/s/w/ir/out/gnmac/./base_unittests
```
(It works fine with ld64.)
MacOSX.sdk/System/Library/Frameworks/CoreFoundation.framework/CoreFoundation.tbd
has a re-export of MacOSX.sdk/usr/lib/libobjc.tbd, so maybe that symbol moved
between dylibs in 10.14, or dyld got more forgiving with incorrect two-level
namespaces or something.</pre>
