[lldb-dev] lldb issues on MacOS

[Greg Clayton]

Nuke your lldb/llvm and lldb/llvm-build folder and run xcodebuild again. The Xcode build doesn't always update and build llvm and you have newer LLDB code and old llvm and clang code. By nuking your llvm and llvm-build folder it will cause the xcodebuild to download and rebuild a fresh and up to date clang and allow you to build and link correctly.
