 > Do we actually still need to ship that lib?
 I think we need to ship `libstdc++.so.6` for the systems where the
 installed version is too old. As we are building using gcc 6.4.0, it seems
 our binaries will require `CXXABI_1.3.10` added with gcc 6.1.0:
 https://gcc.gnu.org/onlinedocs/libstdc++/manual/abi.html

 Some of the distributions built using a gcc older than 6.1.0 are:
 - Ubuntu 16.04LTS (gcc 5.3.1)
 - Centos 7 (gcc 4.8.5)
