netty-tcnative: Crash (Symbol not found: ____chkstk_darwin) under some versions of macOS

After updating to the latest version of ~netty-tcnative~ netty-tcnative-boringssl-static, our Travis CI builds for macOS started reporting crashes. I’ve narrowed the problem down to ~netty-tcnative~ netty-tcnative-boringssl-static 2.0.27 (2.0.26 is fine, and the version of Netty itself doesn’t seem to matter).

I’ve created a minimal reproduction case here: https://github.com/jchambers/netty-tcnative-travis-test. The problem seems to happen when the client and server attempt a TLS handshake. I’ll continue to narrow the problem space.

Here are the details of the Travis instance experiencing the crash:

$ java -Xmx32m -version
java version "1.8.0_112"
Java(TM) SE Runtime Environment (build 1.8.0_112-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.112-b16, mixed mode)

$ javac -J-Xmx32m -version
javac 1.8.0_112
