	* start/crt0.S: Renamed to start/start.S.
	* start/start.S: Formerly start/crt0.S.
	* startup/linkcmds: New file.  GNU linker script that is not
	correct for the target board but links programs.
	* bsp_specs: Use linkcmds.
	* include/Makefile.am, start/Makefile.am startup/Makefile.am:
	Now work.
	* startup/bspstart.c, startup/setvec.c: "#if 0"'ed out references
	to reoutines in assembly that are in turn "#if 0"'ed out.
