Nuke HAVE_BACKTRACE

Browse source 
We do not really need to care if the system provides `backtrace()',
since we will want to test the one provided in libunwind, not the one
that is provided by the system. The `backtrace()' calls should already
be aliased to `unw_backtrace()', but if that is not working for whatever
reason, we can call `unw_backtrace()' explicitly.
