I think the intent was to use single quotes for OPT='two $CFLAGS'.
(You could also do OPT="two \$CFLAGS".) This will pass the string
"$CFLAGS" in OPT, not the value of the shell variable $CFLAGS.
While your shell script will print out: OPT = xtwo $CFLAGSx
This is ok since it will/should get expanded properly in the Makefile.
Or I've totally missed the point too. :-)
