Try this.  The only tricky part is the patsubst converting cman-lib to
cman/lib.
 
USERLAND = cman-lib ccs cman dlm group fence gfs gfs2 gnbd rgmanager
all: $(USERLAND)

$(USERLAND):
	[ -n "${without_$@}" || ${MAKE} -C $(patsubst -,/,$@) all

cman-lib:
ccs: cman-lib
cman: ccs
dlm:
group: ccs dlm
fence: group dlm
gfs:
gfs2:
gnbd: cman-lib
rgmanager: ccs dlm
