try make clean ;; make build ;; make clean

The ;; command is a shell script command that executes the two operands 
and returns 0 if both commands returned false, or -1 if one did not. If 
the leftmost operand returned any other value than 0, the rightmost 
won't be executed. However, do consult the documentation for your 
favorite shell, as I'm not an shell script expert.

Sincerely,
Sigmund
