[Daniel Bertalan via llvm-commits]

https://github.com/BertalanD created https://github.com/llvm/llvm-project/pull/97193

ld64 tests now fail with the following error if the target platform (e.g. `-macosx_version_min`) is not specified:

```
warning: platform not specified
warning: No platform min-version specified on command line
kernelKit can only be used with -r, -kext and -static
```
