Good question and something I'll need to remember to document.

The answer is: it doesn't matter as far as providing dynamic unwind
info is concerned.  libunwind really consists of two parts: the part
to _interpret_ the unwind info, and the part to _provide_ dynamic
unwind info.  Only the former is affected by UNW_LOCAL_ONLY.
