Uhh... now I'm confused. I tried:
%define foo %{foo}X
and using that (with %{foo} defined on the command line) results in:
error: Recursion depth(17) greater than max(16)
15< (empty)

12< (empty)

0< echo foo:
While it works with
%{expand: %%define foo %{foo}X}
as long as %{foo} was defined before.
