To reproduce:
1. Open attached project
2. Open Extra -> il2cppArgs menu, this is an additional menu added by included ExtraSettings script
3. Select Add args checkbox
4. Press Save Values button
5. Change to Android platform
6. Build it and open editor.log

Actual result: when il2cpp is invoked to compile second architecture the arguments are no longer used
Expected result: the arguments should be used both times

The additional arguments are:
> --compiler-flags="-save-stats" --linker-flags="-Wl,-no-gc-sections -save-stats"

Reproduced with: 2018.4.11f1; 2020.1.0a9
Can not check on 2017.4 due to errors.

Note: Editor.log added
