I'm not sure why your subject mentions SCCS suffix rules, but there is a
built-in rule that knows how to convert from a foo.sh to foo, like this
(from "make -p -f/dev/null"):

  %: %.sh
  #  recipe to execute (built-in):
          cat $< >$@
           chmod a+x $@

that's what you're seeing.  As far as I remember this has nothing to do
with SCCS though.  If you don't want this rule, you can delete it via:

  %: %.sh

(no recipe).  See 
https://www.gnu.org/software/make/manual/html_node/Canceling-Rules.html

Or of course you can use "-r" to remove ALL implicit rules, if you prefer.
