Currently we cannot debug rust binaries on darwin (via lldb). The debug symbols seem to be provided by default in a number of files in `target/debug/deps/*.rcgu.o`. As far as I can tell these have hardcoded paths referring to the ephemeral build directory. However, `split-debuginfo=packed` conveniently produces a `.dSYM` file that can be copied to `$out/bin/` and immediately provide debugging information.
