    thp: Disable THP if THP isn't supported by kernel

    Since DL_MAP_DEFAULT_THP_PAGESIZE is defined for x86-64, THP control
    is to set to madvise by default.  If THP is disabled in x86-64 kernel,
    madvise (..., MADV_HUGEPAGE) returns -EINVAL to indicate that THP isn't
    supported.  Add _dl_thp_madvise to disable THP in this case.  This
    fixes BZ #34348.
