	* config.gcc: Don't create crtbegin, crtend on Darwin; do create
	crt2.o.  Rearrange t-darwin makefiles.
	* crtstuff.c [OBJECT_FORMAT_MACHO]: Delete.
	* unwind-dw2-fde-darwin.c: New.
	* unwind-dw2-fde-glibc.c: Correct comment.
	* unwind-dw2-fde.c (__register_frame_info_bases)
	[DWARF2_OBJECT_END_PTR_EXTENSION]: Clear fde_end.
	(classify_object_over_fdes): Use last_fde.
	(add_fdes): Likewise.
	(linear_search_fdes): Likewise.
	* unwind-dw2-fde.h (struct object)
	[DWARF2_OBJECT_END_PTR_EXTENSION]: Add fde_end field.
	(last_fde): New.
	* config/darwin.h (STARTFILE_SPEC): Include crt2.o not crtbegin.o.
	(ENDFILE_SPEC): No crtend.o.
	* config/t-darwin: New.
	* config/i386/t-darwin: Delete.
	* config/darwin-crt2.c: New.
	* config/rs6000/t-darwin: Delete contents duplicated in t-rs6000
	or config/t-darwin.
