Comment (by kencu):

 In the meson.build script, it is assumed that Darwin will have libunwind
 in System:

 {{{
   if host_machine.system() == 'darwin'
     dep_unwind = meson.get_compiler('c').find_library('System')
   else
     dep_unwind = dependency('libunwind', required : _libunwind ==
 'enabled')
   endif
   if dep_unwind.found()
     pre_args += '-DHAVE_LIBUNWIND'
   endif
 }}}

 so that is why we have to add the specific libunwind addition for systems
 that don't have libunwind inside libSystem. Let me try something else...
