## Description
A couple issues that needed fixing:
* Using `--all-features` and `--all-targets` causes us to try to build
the first-party binaries with embedded configuration, which isn't
available from this repository. To unblock CI, we'll only run clippy on
the default feature set for right now.
* Similarly, testing compilation with release configuration was trying
to build the `dev` channel; this switches that over to the `oss`
channel.
