        * configure.host: Set have_crt0 to no for Arm targts when not
        providing syscalls.  Set sys_dir=arm unconditionally.
        Default have_crt0 based on sys_dir.
        * configure.in: Use have_crt0.
        * libc/configure.in: Ditto.
        * libc/sys/configure.in: Ditto.
        * configure: Regenerate.
        * libc/configure: Regenerate.
        * libc/sys/configure: Regenerate.
        * libc/sys/arm/Makefile.am (lib_a_SOURCES): Add aeabi_atexit.c.
        Only build other files when providing syscalls.
        * libc/sys/arm/Makefile.in: Regenerate.
        * libc/sys/arm/aeabi_atexit.c: New file.
