+put vtv_end.o in front of postdep_objects_CXX
+having it after crtendS.o leads to missing zero termination in eh_frame section
+
+This is in line with comment in libgcc/vtv_end.c:
+
+   When the GCC driver inserts vtv_start.o into the link line (just
+   after crtbegin.o) it also inserts vtv_end.o into the link line,
+   just before crtend.o.
