The only way to do it is by writing the rule multiple times, once for
each prerequisite. You can make this slightly more palatable by using a
define variable:
define BUILDOBJ
cmd1
cmd2
...
endef
${WORKDIR}/%${OBJ_SUFF} : %.c
$(BUILDOBJ)
${WORKDIR}/%${OBJ_SUFF} : %.cc
$(BUILDOBJ)
${WORKDIR}/%${OBJ_SUFF} : %.cpp
$(BUILDOBJ)
${WORKDIR}/%${OBJ_SUFF} : %.C
$(BUILDOBJ)
If you REALLY don't want to do that and you are willing to restrict
yourself to GNU make 3.80 or better, you can use eval to do it.
