It is not possible to do currently (such behavior is not really standard).
But it would not be a problem to add an option for ignoring loop check to
the next version.
If you are able to modify sources and recompile BIRD, you could just remove
these lines (1418-1419) from proto/bgp/attrs.c:
if (bgp_as_path_loopy(bgp, a))
goto loop;
