Thanks Volodya for the clarifications.

This actually works only partially. The reason is that I am actually inside a
for loop

for local TARGET in $(TARGETS)
{
    make $(TARGET).myext : 
         my_source_file : 
         @my_action :
         <location>"dir1/dir2/dir3" ;

    constant EXTRA_VAR : $(TARGET) ;
}

unfortunately $(EXTRA_VAR) always takes the value of the last element of the
list of $(TARGETS). This is kind of why I use the "on" construct. Is there any
way of getting that target passed to the action?
