No, the only thing that belongs there is the minimum code to get argc, argv, the addresses of main, _init, _fini, and jump to __libc_start_main. The latter is responsible for things like __progname. If the code were put in crt1.o, all programs would have a reference to __progname encoded into them, which is not something desirable; it would also increase the amount of per-arch code that must be maintained.
