Here are some results for the rusoto test in https://github.com/rust-lang/rust/issues/56068#issue-382175735:

For `--start-lib` I wrapped `--start-lib`/`--end-lib` around all object files.

As I expected `--start-lib` didn't make much difference. The dependencies containing debuginfo that I want to be GCed away are already packaged into static libraries before being passed to the final link.
