    devel/libunwind: use base system unwind.h
    
    - Add --disable-cxx-exceptions so libunwind does not implement the
      _Unwind_* API and does not use its internal unwind.h.  The base
      system libgcc_s provides this API.  This was already the upstream
      default for most architectures.
    - Add --disable-unwind-header to prevent installation of unwind.h.
      Instead, install an unwind.h that forwards to the base system
      unwind.h, but not on FreeBSD 14 where all implementations of
      unwind.h (base, lang/gcc*, and devel/llvm*) are compatible.
