[lldb-dev] Building LLDB when LLVM is built with threading disabled

[Greg Clayton]

Because LLVM enables threading manually, this is the main reason we didn't use their locking primitives.

I am not sure if we recently started using any of LLVM threading stuff that gets disabled (Zach's changes?) when threading isn't enabled in LLVM, but I don't believe we have enabled threading in LLVM builds.

Can you elaborate on what is making the build fail now after you disable threads?
