Comment 3 for bug 1862318

The PR link I botched above:
https://github.com/snapcore/snapcraft/pull/2918

The snapcraft `edge` channel will treat this error as a warning.
To switch: `sudo snap refresh snapcraft --channel=edge`.

The PR above will address the error, but snapcraft will log a different warning:
This part is missing libraries that cannot be satisfied with any available stage-packages known to snapcraft: - libc.musl-x86_64.so.1

There a a couple of reasons for this (triggered by the unusual use of musl). I'm going to create a new bug report to track that separately.
