I think that assuming libunwind by default is the better choice.  Assuming
that GCC is installed is an odd assumption (I don't see anywhere in the
docs that in order to use clang, you *must* have gcc installed in the
standard location).  Users can easily change the default behaviour with the
flag if they desire.
