    aarch64: ERRAT_NONE is not zero, so test against it
    
    erratum_84319_opts starts at ERRAT_NONE = (1 << 0), so a plain boolean test
    on fix_erratum_843419 is true even when no erratum workaround was asked for.
    Every other use in the file tests against ERRAT_NONE or masks with ERRAT_ADR /
    ERRAT_ADRP.  Two do not.
    
    The bare test dates from the conversion of fix_erratum_843419 from an int to an
    enum for PR ld/24373.
    
    Having the workaround on by default all the time is, of course, undesirable as
    it costs link-time and is not what the user has asked by default.
    
    Tested on aarch64-none-linux-gnu.
    
    bfd/
            * elfnn-aarch64.c (elfNN_aarch64_write_section): Test
            fix_erratum_843419 against ERRAT_NONE.
            (elfNN_aarch64_late_size_sections): Likewise.
