This includes building universal binaries (for arm64 and x86_64) and targeting an older minimum deployment target. (Before 1919720fdd348ca568b235bf3f1357c198eccd15 in llvm-project, Jan 2022, building lldb's debugserver failed, if building for macOS for multiple architectures, or for an architecture other than the current host.)
