[IL2CPP] Extremely high memory usage when building for Linux platform
Reproduction steps:
1. Open the attached “IN-90045” project
2. Open the Build Settings window (File > Build Settings)
3. Make sure “Linux” is the selected platform
4. Make a Clean Build of the project
5. Observe the Build progress
Expected result: The Build finishes successfully
Actual result: Memory usage keeps increases on “Linking GameAssembly.so (x64)” task
Reproducible with: 2021.3.45f1, 2022.3.53f1, 6000.0.31f1, 6000.1.0a8
Reproducible on: Ubuntu 24.04, Windows 10, Arch (user)

Resolution Note:
I will mark this as designed, as the issue is caused by the C++ Compiler configuration being set to Master. As stated in the documentation: "Master configuration enables all possible optimizations, squeezing every bit of performance possible. For instance, on platforms that use the MSVC++ compiler, this option enables link-time code generation. Compiling code using this configuration can take significantly longer than it does using the Release configuration. Unity recommends building the shipping version of your game using the Master configuration if the increase in build time is acceptable."
