That's a bit annoying, especially since you're already using raw syscall numbers anyways. Here's how to make it static:

  .intel_syntax noprefix
  
  #include <sys/syscall.h>
  
  #define UNIX_SYSCALL 0x2000000
  
  .globl start
  start:
      mov rax, UNIX_SYSCALL | SYS_write
      mov rdi, 1
      lea rsi, text[rip]
      lea rdx, length
      syscall
      mov rax, UNIX_SYSCALL | SYS_exit
      xor rdi, rdi
      syscall
  
  text:
  .asciz "Hello, world!\n"
  .equ length, . - text

Compile that with clang -static -nostdlib.

You don't have to change the source or compile with `clang` -- switching the LD command to:

  ld -arch x86_64 -o hello hello.o -macosx_version_min 10.8 -static -e _main

is sufficient if you're determined to violate the OS vendor's compatibility requirements.

That works too, but I'm lazy :P
