I think the restrict system headers check should probably be removed at this point. There are too many cases where we do actually need to include system header (such as what's mentioned above).

It's important for overlay mode that we include the system's definitions of various structs, such as for fenv or epoll_wait. In fullbuild mode our headers will be used regardless of how we include them.
