Linux IL2CPP build fails while using Windows Editor when there are spaces in %USERPROFILE%
Reproduction steps:
1. Open a new or an existing project
2. Go to Edit > Project Settings... > Player > Other Settings and select the IL2CPP Scripting Backend
3. Import the Toolchain Win Linux x64 package
4. Build the project
Expected result: Build succeeds
Actual result: Build fails
Part of the error:
stdout:
Running il2cpp.exe in server GC mode.
Either unknown arguments were used or one or more assemblies could not be found :
PartOfName\AppData\Local\unity3d\cache\sysroots\windows-x86_64-linux-x86_64\llvm-9.0.0-1\bin\ld.lld -target x86_64-glibc2.17-linux-gnu
Reproducible with: 2019.4.17f1, 2020.1.17f1, 2020.2.2f1, 2021.1.0b1
Could not test with: 2018.4.30f1 (due to the option to build for Linux IL2CPP not being available on this version)
Notes:
- To import the Toolchain package, include this line in the manifest.json file within the project directory:
"com.unity.toolchain.win-x86_64-linux-x86_64": "0.1.17-preview"
- Linux and macOS don't have the option to name the user profile folder with a space in the name, so the issue is not reproducible on those systems

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 (the path created before)
- Reboot computer.
Now try to build again and it should work!!
Hope this helps someone!

I still get this error. This is the environment:
- Unity 2021.3.11f1
- Windows11 with user folder with a white space between words like "ABC DEF"
- Toolchain Version 2.0.2
