Sort of.
I was thinking of making the optional rules have
the osc_ rule name prefix (optional syntax check), rather than
the usual "sc_" prefix.  Then, if a project doesn't want the default,
it would define a variable in cfg.mk to select something different.

Let the form of the rule name define the sets.
Currently it's done like this with the "sc_" prefix:

  _cfg_mk := $(shell test -f $(srcdir)/cfg.mk && echo '$(srcdir)/cfg.mk')

  # Collect the names of rules starting with `sc_'.
  syntax-check-rules := $(sort $(shell sed -n 
's/^\(sc_[a-zA-Z0-9_-]*\):.*/\1/p' \
                          $(srcdir)/$(ME) $(_cfg_mk)))
  .PHONY: $(syntax-check-rules)
