/* Below comes the architecture-specific code. For each architecture, we have
 * the syscall declarations and the _start code definition. This is the only
 * global part. On all architectures the kernel puts everything in the stack
 * before jumping to _start just above us, without any return address (_start
 * is not a function but an entry pint). So at the stack pointer we find argc.
 * Then argv[] begins, and ends at the first NULL. Then we have envp which
 * starts and ends with a NULL as well. So envp=argv+argc+1.
