I think there's more. I added the import and the runtime built, 
however, the application now fails to link because it can't find 
`unw_getcontext` etc. However, looking in `/usr/include`, I see:

```c
#define unw_getcontext(uc)              unw_tdep_getcontext(uc)
```

This include file is in `/usr/include/aarch64-linux-gnu`, which I 
guess might mean that the libunwind ABI interface differs across 
architectures :(
