What this PR does / why we need it:
When a multi-platform build fails and we hand an error back, add the platform to the error's context so that it's easier to tell at the end of the log which platform the build failed for.
How to verify it
Build with multiple
--platform
values (e.g.--platform linux/arm64,linux/amd64,linux/ppc64le,linux/s390x
), and have one or more of them fail. Example:Which issue(s) this PR fixes:
None
Special notes for your reviewer:
Nothing earth-shattering, just something to make troubleshooting a little bit easier.
