In for loop values, introduce a dummy to protect against empty list
In constructions such as 'for x in $(MAKEVAR); do ...', there's the
possibility that $(MAKEVAR) is en empty value. Some shells don't like
that, so introduce a dummy value that gets discarded:
for x in dummy $(MAKEVAR); do
if [ "$$x" = "dummy" ]; then continue; fi
Closes RT#4459
