emacs-grep was introduced in late 2007:

revno: 82277
committer: Juri Linkov <juri <at> jurta.org>
timestamp: Fri 2007-11-23 00:32:05 +0000
message:
  (grep-process-setup): Set envvar "TERM" to "emacs-grep".
  Set envvar "GREP_OPTIONS" to "--color=auto" instead of "--color=always".


My guess is that Suse changed if this worked for you on an Emacs newer than 
this change.
