I don't have 12.04 to hand, but I can reproduce this behaviour on 12.10.
However Ubuntu 10.04 behaves like Debian unstable (the position of
--libs doesn't matter).

I'm not sure why the behaviour is different between versions, but if you
link against multiple libraries, you usually need to list them such that
each library is before any other libraries which it uses symbols from,
so it's perhaps not totally surprising to need to list the libraries
after the objects (or in this case sources) which use them.
