Currently our Linux binaries aren't quite as portable as they otherwise could be. There's two primary reasons for this, and one of them is that the binary is produced in a relatively recent Linux distribution (Ubuntu 16.04) which means it has a relatively recent requirement in terms of glibc versions. On OSX/Windows we can set some flags to rely on older libc implementations, but on Linux we have to actually build against an older version. This commit switches the container for the build to CentOS 6 instead of the default Ubuntu 16.04. The main trick here is also finding a C++11-capable compiler to compile wabt. Turns out though there's a helpful tutorial for this at https://edwards.sdsu.edu/research/c11-on-centos-6/ and it was as easy as installing a few packages. The second portability concern of our Linux binaries is that they link dynamically to `libstdc++.so` which isn't always installed on target systems, or even if it is it may be too old or have a different ABI. This is solved by statically linking to `libstdc++.a` in the build on Azure by doing a bit of trickery with libraries and what's available. After these results the glibc requirements drops from 2.18 (released in 2013) to 2.6 (released in 2007) and avoids the need for users to have libstdc++.so installed. We may eventually want to investigate fully-static musl binaries, but finding a musl compiler for C++ is something I'm not that good at, so I figure this is probably good enough for now.pull/274/head
