Comment:
Looking a bit into it, I think I've got it building with our current version by setting the `profile = "user"` toplevel option which will use default options from `masterdir/builddir/rustc-1.63.0-src/src/bootstrap/defaults/config.user.toml`:

```
# These defaults are meant for users and distro maintainers building from source, without intending to make multiple changes.
[build]
# When compiling from source, you almost always want a full stage 2 build,
# which has all the latest optimizations from nightly.
build-stage = 2
test-stage = 2
doc-stage = 2
# When compiling from source, you usually want all tools.
extended = true
```

I think this would make sense to adopt those options or include `profile = "user"`. I'm still test building things while also doing firefox-esr builds in parallel so I'm not able to fully verify if every target builds fully.
