To reproduce:

1. Download and open attached "UnityInterpreter.zip" project.
2. Change build target to something that supports IL2CPP (android for example).
3. Set scripting backed to IL2CPP.
4. Build the project.

Expected result: Project successfully builds without any errors.
Actual result: Project is not built. Following 3 errors appear in the console:

• IL2CPP error for method 'IronPython.Runtime.List IronPython.Modules.Builtin::range(IronPython.Runtime.CodeContext,System.Object,System.Object,System.Object)' in assembly...
• Failed running E:\Unity Installations\2017.2\2017.2.1p1_edf5bdf50eb0\Editor\Data\il2cpp/build/il2cpp.exe --convert-to-cpp --emit-null-checks --enable-array-bounds-check --development-mode --compile-cpp --libil2cpp-static --platform="Android" --architecture="ARMv7" --configuration="Release"...
• Exception: E:\Unity Installations\2017.2\2017.2.1p1_edf5bdf50eb0\Editor\Data\il2cpp/build/il2cpp.exe did not run properly!

Reproduced with: 2018.1.0b1, 2017.3.0f3, 2017.2.1p1, 2017.1.2p4, 5.6.5f1.

Notes: Does not reproduce with Mono scripting backend. Issue seems to be caused by "PythonInterpreter" plugin.
