per shared library. So in any given whole process image, we may have
multiple definitions of each of these symbols. In order to prevent
these definitions from conflicting with one another, and in order to
ensure that the proper lists are used for the initialization/finalization
of each individual shared library (respectively), we give these symbols
only internal (i.e. `static') linkage, and we also make it a point to
refer to only the __CTOR_END__ symbol in crtfini.o and the __DTOR_LIST__
symbol in crtinit.o, where they are defined. */
