rustc built from a source tarball reports it's `nightly`

[psumbera]

On Solaris I get following:

rustc --version
rustc 1.77.0-nightly (aedd173a2 2024-03-17) (built from a source tarball)

I'm confused about -nightly part.

Is it expected behavior?

What is the config.toml settings and command you used to build?

There is a setting in config.toml for setting the channel.

I had to add --release-channel=stable. Which results in channel = 'stable' in config.toml. This resolved the issue.

Question is whether channel shouldn't be always stable when building from official source tarball.

Currently it's not possible because we don't have any state file in the source tarballs to determine whether they are stable, beta or nightly.

I was wrong, see #124618 (comment).

src/ci/channel should indicate what channel the source distribution is for.
