[Linux] [IL2CPP] Building for Linux with IL2CPP from Windows fails if your system username contains a space
How to reproduce:
1. Create a new Windows user with a name containing a space
2. Create a new Unity project
3. Select IL2CPP as the scripting backend (Edit > Project Settings > Player)
4. Select Linux as the target platform (File > Build Settings)
5. Click Build
Expected result: The project builds successfully
Actual result: The project build fails with Unity.IL2CPP.Building.BuilderFailedException
Reproducible with: 2019.4.28f1, 2020.3.13f1, 2021.1.14f1, 2021.2.0b2, 2022.1.0a1

Found a workaround!!
Basically just change the linux toolchain directory (by using an Environment Variable):
- Create a new folder to have the toolchain files (I used "C:\UnitySysroots")
- Go to "/AppData/Local/unity3d/cache/sysroots/" and move those 2 folders into the new one.
- On "Unity Project Settings > Toolchain Management" disable this option: "Install toolchain packages automatically"- Win + R, type "sysdm.cpl"
- "Advanced tab" + click "Environment Variables"
- On "User variables" and "System variables" (I did both just to be safe) click "New":
- Variable name: UNITY_SYSROOT_CACHE
- Variable value: C:\UnitySysroots (or some other path *without spaces*)
- Reboot computer.Now try to build again and it should work!!
Hope this helps someone!
