I am building LLVM + all the included projects on top of GCC in a non standard location.
The problem I am having is that in the execution of the test-suite, several tests related to `libunwind` and `libc++` link to `libatomic`, but during the execution of the compiled test with [run.py](https://github.com/llvm/llvm-project/blob/main/libcxx/utils/run.py) the environment is not carried over.
When running the test-suite on my WS where a version of `libatomic` is present also in a standard location this is not a problem (guess it could still be if the version i am compiling of top of is incompatible with the one i have by default on my system?).
If the system does not have `libatomic` in a standard location (eg the build node I am using for testing), the test-suite gives many false failures of the type

I've looked a little to see if there is some option to pass to `LIT_ARGS` to bypass this by allowing all or some environment variable to be carried over to the test execution, but I haven't found anything.
The only other solution would be to hack the `run.py` or the configuration file before running the test.
I was wondering while probably niche, if this should be supported by the test-suite (or if it already is and I've missed it)
