I guess that you mean that you don't want an error message if a glob
pattern matches nothing.

There is an option CSH_NULL_GLOB (use setopt CSH_NULL_GLOB) that seems
to make zsh behave like csh.

>>From man zshoptions:

          CSH_NULL_GLOB
               If  a  pattern  for  filename  generation  has  no
               matches,  delete  the  pattern  from  the argument
               list; do not report an error unless all  the  pat-
               terns  in  a  command  have no matches.  Overrides
               NULLGLOB.

There is also an option NULL_GLOB

          NULL_GLOB (-G)
               If  a  pattern  for  filename  generation  has  no
               matches, delete the pattern from the argument list
               instead  of   reporting   an   error.    Overrides
               NO_NOMATCH.

But there is also a way to set NULL_GLOB locally for just one glob
pattern.

	       alias suber='rm *.toc(N) *~(N) *.aux(N)'

Should do the trick.
