This indeed would be very cool! Right now things work relatively well with the biggest pain being the acquisition of std for your target.
If std and core could be made into first-class crates, then you could get rid of the need to find a pre-built version of libstd for your target. It would just be built when needed by a project.
This is what we currently do in zinc for core via the hack here: https://github.com/hackndev/zinc/blob/master/Cargo.toml#L27. Zinc doesn't use std (for obvious reasons). Right now, targeting a raspberry pi is much harder than it should be as a result of having to having to find an appropriate cross-compiled std.
That is, I want the steps for cross-compilation to be:

1. Execute `cargo build --target=foo`.
2. There is no step 2.
