How to reproduce:
1. Open the user attached "strip-test.zip" project
2. Change the Target Platform to Linux (File -> Build Settings) and turn on "Development Build"
3. Change the Scripting Backend to IL2CPP (Edit -> Project Settings -> Player -> Other Settings)
4. Build the project (File -> Build Settings -> Build)
5. Navigate to the "project folder"/Temp/StagingArea/Data/Managed folder and see if MethodsToPreserve.xml exists
6. Build the project again
7. Navigate to the "project folder"/Temp/StagingArea/Data/Managed folder again

Expected result: MethodsToPreserve.xml is created after both builds
Actual result: MethodsToPreserve.xml does not get created after the second build

Reproducible with: 2021.2.15f1, 2022.1.0b11, 2022.2.0a7
Couldn't test with: 2019.4.36f1 (Requires sysroot toolchain package installed, even though it is), 2020.3.31f1 (Necessary folders did not get generated)

Note:
- For constant reproduction delete the Library and Temp folder before repeating steps
- Building project requires cross-compilation toolchain package
- Tested 2021.2 with MacOS
- 2022.1 and 2022.2 can only be built on Linux
