@conradgrobler @andrisaar before I spend too much time into this, is there any obvious reason why it should not work?

Yes, it won't pick up .cargo/config.toml filed.

But I moved things so it's not necessary any more. The target is specified per-crate, and the extra flags are in the top level cargo config. Building the stdlib is not actually necessary as long as we install the target in the dockerfile (which we should do anyways).

Ah. I haven't had a closer look, but I documented some issues in #2654 back in the day.

It turns out this works for the most part, except cargo docs and cargo udeps, which for some reason get confused by the lack of stdlib for some of the targets.
