[Lldb-commits] [lldb] [lldb][rpc] Add sysroot to lldb-rpc-gen test suite invocation (PR #151291)

[Chelsea Cassanova via lldb-commits]

https://github.com/chelcassanova created https://github.com/llvm/llvm-project/pull/151291

When running the lldb-rpc-gen tests On Darwin platforms, the sysroot needs to be added to the test invocation. Without it, basic includes will not be resolved and the test will fail.
