Gradle build fails with /lib64/libstdc++.so.6: version `GLIBCXX_3.4.20’ not found

Bug:

Hello!

I am trying to contribute the Lets-Plot package to conda-forge:

https://github.com/JetBrains/lets-plot

That project is based on Kotlin Native with Python API and builds with Gradle.
After running local build for Linux python build-locally.py linux64, I got the following error:

This is a one-time action performed only on the first run of the compiler.
