Yes, -j1 is the right and obvious solution but I think you have .NOTPARALLEL completely backwards. Here's what the manual says:
If .NOTPARALLEL is mentioned as a target, then this invocation of make will be run serially, even if the ‘-j’ option is given ... Any prerequisites on this target are ignored.
