Add nolibc support for m68k. Should be helpful for nommu where linking libc can bloat even hello world to the point where you get an OOM just trying to load it.

/* 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 point). 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.
