Standalone installation instructions doesn't have links for other rustup components

https://forge.rust-lang.org/infra/other-installation-methods.html#standalone, https://static.rust-lang.org/dist/rust-std-1.47.0-armv7-unknown-linux-gnueabi.tar.xz. It looks like this is generated by

rust-forge/blacksmith/src/lib.rs

Line 140 in a919848

for target in &self.rustup {

, but I can't see where rustup is populated.

Looks like it comes from https://raw.githubusercontent.com/rust-lang/rustup.rs/stable/ci/cloudfront-invalidation.txt, which is also missing that target.

No, this is due to another part of the source code.

rust-forge/blacksmith/src/lib.rs

Lines 81 to 124 in 080c154

	for &channel_name in CHANNELS {
	let channel_url = format!("{}{}.toml", CHANNEL_URL_PREFIX, channel_name);
	let content = reqwest::blocking::get(&channel_url)?.text()?;
	let rust = toml::from_str::<crate::channel::Channel>(&content)?
	.pkg
	.rust;
	log::info!(
	"Found {} targets for {} channel (v{})",
	rust.target.len(),
	channel_name,
	rust.version
	);
	let vers = rust.version.split(' ').next().unwrap().to_string();
	let platforms = rust
	.target
	.into_iter()
	.filter_map(|(target, content)| {
	if content.available {
	Some(target)
	} else {
	None
	}
	})
	.collect::<Vec<_>>();
	if channel_name == "stable" {
	blacksmith.stable_version = Some(vers.clone());
	}
	for platform in platforms {
	let entry = blacksmith
	.platforms
	.entry(platform)
	.or_insert_with(Platform::default);
	match channel_name {
	"stable" => entry.stable = Some(vers.clone()),
	"beta" => entry.beta = true,
	"nightly" => entry.nightly = true,
	_ => unreachable!(),
	}
	}
	}

This generates the list of platforms with the rust component available (due to the .pkg.rust), which only catches platforms with a full host compiler. We'd need to create a separate list with the links to the rust-std components.
