mklibgcc.in (lib2funcs): Remove _exit.

        * mklibgcc.in (lib2funcs): Remove _exit.
        * libgcc2.c: Remove L_exit.
        * gbl-ctors.h: Remove declarations dependend on NEED_ATEXIT.

        * system.h: Poison NEED_ATEXIT, ON_EXIT, EXIT_BODY.

        * doc/tm.texi (Misc): Remove NEED_ATEXIT, ON_EXIT, EXIT_BODY.
