Workaround Mac arch issue

Browse source 
Temporarily works around an issue on Mac where the system version of
NXGetLocalArchInfo is returning x86 information on x86_64 devices,
which results in dump_syms failing on said devices. Instead, the
Breakpad implementation of NXGetLocalArchInfo, which is meant for
dump_syms_mac on Linux, will be used until the system version is fixed.
