A quick workaround should be something along these lines:

  for f in $('ls' /usr/pgsql-10/lib/*postgis*-3.so); do
    l=$(echo "$f" | sed 's/-3\./2.5./')
    ln -vs "$f" "$l"
  done

BUT I'm wondering: why would you want to upgrade to 3.1.2 when the
latest PostGIS version in the 3.1 branch is 3.1.8 ?

I'm asking because according to the NEWS file the bug you report
was fixed in 3.1.5:
