Introduced in https://github.com/llvm/llvm-project/pull/91150. Not needed anymore as https://github.com/llvm/llvm-project/pull/92041 fixed the root cause. `ENAMETOOLONG` and `EOVERFLOW` are well defined in `<linux/errno.h>`.

Post mortem: Due to the previously missing inclusion of `<linux/errno.h>` (fixed with https://github.com/llvm/llvm-project/pull/92041), I misinterpreted an undefined macro issue during the development of https://github.com/llvm/llvm-project/pull/91150 as being caused by a missing definition rather than by the missing inclusion of the linux header. I realized too late that `ENAMETOOLONG` and `EOVERFLOW` were correctly defined in `<linux/errno.h>` and that it was my missing inclusion that caused the problem.
