Clarification on the Use of -Wl,--unresolved-symbols=ignore-in-object-files Linker Flag

The build process utilises the linker flag -Wl,--unresolved-symbols=ignore-in-object-files during the compilation. I wanted to gain a deeper understanding of the purpose behind this particular flag in the context of this project.

Reasoning: Is there a specific reason or dependency within the project that requires ignoring unresolved symbols in object files during the link phase?

Potential Impacts: If we were to omit this flag, are there any known issues, edge cases, or behaviours we should be aware of?
