-/* The GNU and SGI linkers differ in their implementation of -init and -fini.
-   With the GNU linker, there can only be a single -init option, and the
-   linker simply sets DT_INIT to that value.  gcc's initialization and
-   finalization code can go directly in .init, with the prologue and
-   epilogue of the main initialization routine being provided by external
-   object files (*crti.o and *crtn.o in this case).
-
-   The SGI linker instead accepts several -init options.  It will set DT_INIT
-   to a linker-created function (placed in .init) that calls each of the -init
-   functions in turn.  If there is any user code in .init, this linker-created
-   function will be placed after it.  Note that such user code is not treated
-   specially; it will only be called if the -init options arrange for it to
-   be called.
-
-   In theory, the SGI model should allow the crti, crtn and intermediate code
-   to go in .init, just like it can with the GNU linker.  However, doing this
-   seems to confuse the linker and triggers an internal error:
-
-      ld32: FATAL   2  : Internal: at ../../ld/mips_code.c mips_code_fixup()
-	 text section overflow!
-
-   (seen with MIPSpro 7.30).  We therefore put everything in a special
-   .gcc_init section instead.  */
