Comment (by mascguy):

 I was hoping we might be able to handle this via arguments to `rustc`,
 etc, but perhaps it's not that straightforward?

 Regardless, this is purely a nice-to-have, to reduce the verbosity of our
 build logs. So if it's not easy or practical, I'm fine with closing.

 Anyone else, thoughts?
