I'm not sure where the error leading up to building failure is coming from

/usr/local/bin/llvm-ar: error: script line 1: unknown command: OPEN

perhaps it has something to do with a recent update to ossfuzz compiler toolchain builder pack?

Can confirm there was a toolchain roll on Aug 11 https://chromium.googlesource.com/chromium/src/+/ce8f94ef957739b440ea78875bf3d2ea0382003d

However, solidity's build started failing with same issue on August 10 so not sure this is related: https://oss-fuzz-build-logs.storage.googleapis.com/log-70ac0797-dd9c-4ebd-8dbc-10311c0dfb62.txt

Can you replace the from line in dockerfile to FROM gcr.io/oss-fuzz-base/base-builder@sha256:a752ca08bc5b2b3cc1354ca50f09c46211dd52663d295fd09023a431237dd2b8 so we can try building with old toolchain?

Just pushed the commit with this change.

OK. Please undo. Looks like this isn't a toolchain issue.

It looks like a build issue in a dependency. Have created an issue to track it: ethereum/evmone#373
