Makefile : delimit a shell variable ($$var)

I have a shell variable in a for loop and I would like to indicate the end of the name of this variable:

$(DEBUG)for extblock in $(EXT_BLOCKS_LIST); \
    do cat syn/ext_$$extblock_syn.tcl >> syn/$(SYN_TCL_SCRIPT); \
done;

My variable is only $$extblock but make takes $$extblock_syn as variable.

I don't achieve to put () correctly. Is there another character to indicate the end of a variable name?

Try this:

do cat syn/ext_$${extblock}_syn.tcl >> syn/$(SYN_TCL_SCRIPT);\

Braces can be used as delimiters. Also see the bash manual on shell parameter expansion.
