Many thanks.

Make only looks at the unexpanded command line and searches for the
strings '$(MAKE)' or '${MAKE}'. It does not look at the expansion of
the command line (it cannot, since after expansion obviously there will
be no $(MAKE) or ${MAKE}... they are expanded!)
Your unexpanded command line is the string '$(LOOP)', which obviously
does not contain the text '$(MAKE)' or '${MAKE}'.
Just exactly as the error message says, you need to add a "+" to the
beginning of the rule. Change:
LOOP = @for ssp in $(SSP); do \
...
to
LOOP = +@for ssp in $(SSP); do \
...
