node-argon2: Argon2 build fails on GCC 4.8

Steps to reproduce

1. Install argon2 v0.17.2 package via npm

Expected behaviour

The package is installed correctly, the build of the C++ argon2 binary does not fail. The build did not fail with argon2 v0.16.2

Actual behaviour

The build of argon2 v0.17.2 binary fails with following errors:
