Ran across a CRITICAL after downloading the native_engine.so from bintray

@tcco : Hey Tim! The native engine is built on debian wheezy, and currently requires at least GLIBC 2.13. I'm working to lower the GLIBC to 2.12 via #4896, but as it stands, I don't think we'll be able to build on a system that uses musl.

It would be a goal to link statically against musl at some point, but we currently have other native dependencies (gRPC I think? cc @illicitonion) that don't make that easy, unfortunately.

If it's not an option to use a different linux distribution, it should in theory be possible to rebuild in the 1.3.x branch on alpine, and then host the native binary yourself at either a URL or file link with the --binaries-baseurls option.

@stuhood This is great insight. Thanks for that - I'll probably opt out of Alpine knowing the mismatch. Out of curiosity I found this, which could provide a hack fix.

Primary reason to go with Alpine was the light-weighted nature. Really am looking for compatibility and portability when interacting with pants! Which linux disto would you recommend?

Appreciate it
