FYI: portability tweak for Tru64 V4.0.

[Jim Meyering]

        Portability to Tru64 V4.0.
        * src/system.h (ftello) [!HAVE_FSEEKO && !defined ftello]:
        Define inline replacement function.
        This (along with a yesterday's fix for autoconf's
        _AC_SYS_LARGEFILE_MACRO_VALUE macro) makes it so coreutils
        now builds once more on Tru64 V4.0.  Reported by Nelson Beebe.
