    Noted by @tahonermann in [this thread](https://discourse.llvm.org/t/testing-libc-documentation-page-is-incorrect-or-incomplete/64200). and [confirmed](https://discourse.llvm.org/t/testing-libc-documentation-page-is-incorrect-or-incomplete/64200/4) as an issue by @ldionne in that same thread.

The reported reproducer was:
```
$ ../llvm-project-build/bin/llvm-lit -sv libcxx/test/std/depr/depr.c.headers/stdlib_h.pass.cpp
llvm-lit: /home/tom/projects/llvm-project/libcxx/test/lit.cfg.py:7: fatal: You seem to be running Lit directly -- you should be running Lit through <build>/bin/llvm-lit, which will ensure that the right Lit configuration file is used.
```

I'm seeing the same failure with a test I was trying to run individually. I wasn't able to find an existing issue, so creating this one to track it.
