Summary: It's a small C utility. It should belong to `clib` directory. Also, `#include "../foo"` does not seem to be a good pattern. It makes include files harder to follow and make code movement more difficult. Since `clib` is already included in `-I` during compilation, remove `../`. Test Plan: `make clean local`. It still builds.
