 Review comment:
   My first attempt at a fix for this did something similar (modifying the 
stack pointer in `os_arch_task_stack_init()`) but I didn't like that the user 
may end up with a slightly smaller stack than they specified. Let me know If 
you would rather I did this to fit in with the x86 sim port.
   
   `typedef uint32_t __attribute__((aligned(8))) os_stack_t;`
   
   I couldn't get this to work, looks like it aligns the elements and not the 
array?
   
   `repos/apache-mynewt-core/kernel/os/src/os.c:48:1: error: alignment of array 
elements is greater than element size`
