[As I mentioned before, build-presets.ini is where you look](https://forums.swift.org/t/swiftc-built-from-source-fails-to-compile-anything-on-ubuntu/34749/5) to figure out how to use the build-script. I see several `skip-test-lldb` and `lldb-test-swift-only` in there, so it's likely you have to be careful how you run the full lldb testsuite, if it can be run at all.

Find a preset config in there that runs the lldb tests you want and either run that or the flags that it bundles, then you can experiment with changing it if wanted.
