Actually, that's probably a bad idea.  It's almost trivial to convert
the list to a circular one.  Then alpm_list_last(foo) would just be
foo->prev;

There should never be a case when this would cause a problem (i.e.
some sort of "scan backward until ->prev is null" function would only
be useful in the case of bad design).
