A few hints:
Another one for debug builds on Linux is using split debug info: -DLLVM_USE_SPLIT_DWARF=ON. This speeds up links dramatically (and reduces memory consumption) as long as you've got a new enough gdb (I think lldb is still not quite up to it). It has no effect on macOS though, because a similar configuration is just how things work there.
