yeah I can force it to spit it out by adding:
```
    println!("cargo:rustc-link-arg-bins=--print-memory-usage");
```
to `build.rs`
but I also have to set:
```
export RUSTC_LOG=rustc_codegen_ssa::back::link=info
```
in the console to see that output. Not ideal, but _something_. A better static memory usage output would definitely be useful, but I can work with that for now. :)
