----------------
This is the one in NetBSD already (although as `return 0`). @joerg also has another case there:
```
    if (encoding == DW_EH_PE_omit)
      return 0;
    if (encoding == DW_EH_PE_aligned) {
      addr = (addr + sizeof(pint_t) - 1) & sizeof(pint_t);
      return getP(addr);
    }

  // first get value
```

@joerg would you upstream these changes from NetBSD's copy?
