(Linux) Build failure against 2024-09-25 nightly toolchain -- error: member operator '==' of protocol 'SpanBase' must have at least one argument of type 'Self'

[clackary]

There's a build failure against recent Swift development snapshots (the one I used here was 2024-09-25).

root@7481e59c0960:/project/opentelemetry-swift# /home/dev-toolchain/swift-DEVELOPMENT-SNAPSHOT-2024-09-25-a-ubuntu22.04-aarch64/usr/bin/swift build

Building for debugging...

117 |         return lhs.context.spanId == rhs.context.spanId
