That's just too old.

    qemu/osdep: Remove fallback for MAP_FIXED_NOREPLACE

    In order for our emulation of MAP_FIXED_NOREPLACE to succeed within
    linux-user target_mmap, we require a non-zero value.  This does not
    require host kernel support, merely the bit being defined.

    MAP_FIXED_NOREPLACE was added with glibc 2.28.  From repology.org:

                      Fedora 36: 2.35
              CentOS 8 (RHEL-8): 2.28
                      Debian 11: 2.31
             OpenSUSE Leap 15.4: 2.31
               Ubuntu LTS 20.04: 2.31
