It's need to link with `libprocstat`, which is need for the 
`filestat` struct definition, and it's `proc_*` functions used
is `get_filename_from_fd` function, however the function is declared
static, which emits an `unused function warning`, but compiles
successfully.

The linker errors only when the `get_filename_from_fd` is used in
`freebsd_exec_common` function.
