On an Ubuntu Xenial system, I see:

/opt/wasi-sdk/bin/clang: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.22\' not found (required by /opt/wasi-sdk/bin/clang)

This hasn't been an issue with past releases, and seems to be new since basing the Dockerfile on Debian stretch rather than Xenial. Could we consider switching back to Xenial, or an older version of Debian that would pull in a compatible libstdc++?

Sure, we can try that. I hadn't realized when I submitted #65 and stretch was more recent than xenial. I guess we could try going back to jessie which pre-dates both of them.

It's odd because Xenial is based on stretch (according to /etc/debian_version at least), but maybe stretch has gotten newer C++ libraries over the years?

When checking undefined symbol list, ignore certain llvm buildins

These can vary between llvm version.  For example a recent upstream
