Use a symlink to share the console code in hello_world. Not ideal,

I'm hitting a build error:
error[E0050]: method `alloc` has 2 parameters but the declaration in trait `core::alloc::AllocRef::alloc` has 3
Updating the version of linked_list_allocator fixes it. I updated
heapless to while I was at it.
