Based on a quick check of the disassembly, _exit is dynamically linked. It appears that because of that dynamic linkage, there's some information stored for dyld to use. That data seems to be split across a few sections which are loaded with padding.

It's also a fat binary. It contains both an X64 and AArch64 version.

I should add that it really is doing nothing other than calling exit:

    EntryPoint:
        push       rbp
        mov        rbp, rsp
        xor        edi, edi
        call       imp___stubs__exit  
    imp___stubs__exit:
        jmp        qword [_exit_ptr]
