    gdb: Always suppress stringop-overread warning in debuginfod-support.c
    
    Just like on s390x with g++ 11.2.1 and ppc64le with g++ 11.3.1 g++ 11
    on hppa produces a spurious warning for stringop-overread in
    debuginfod_is_enabled for url_view. Just always suppress it on all
    arches.
    
    https://sourceware.org/bugzilla/show_bug.cgi?id=29198
    
    gdb/ChangeLog:
    
            * debuginfod-support.c (debuginfod_is_enabled): Always use
            DIAGNOSTIC_IGNORE_STRINGOP_OVERREAD.
