test: replace x86_64-bare-metal.json with x86_64-unknown-none

This avoids breakage such as #460 in the future.

Thanks!

Looks like cargo xbuild does not support .cargo/config.toml files yet. Maybe it's enough to change these lines:

https://github.com/rust-osdev/cargo-xbuild/blob/4dd5dbb579bca07e4066cd25a4c99b36fb5ea1ae/src/cargo.rs#L187-L192

Alternatively, we could finally switch our test framework to -Zbuild-std.

@Freax13 @josephlr What do you think?

Switching to -Zbuild-std sounds good to me.

Switching to -Zbuild-std sounds good to me.

I'll take a look in the coming days. :)

I have now pushed commits to gradually move away from xbuild to -Zbuild-std to using x86_64-unknown-none (without -Zbuild-std).

What do you think? :)

Great, thanks!
