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
