You could just deal with this in make by creating targets that re-run make with the arguments you want. Then you don't have to change Vim settings to alter the way make runs. It's probably not an important distinction but doing it in the Makefile lets other developers benefit from the change as well.

Example:
# Makefile
parallel:
make -jX all

serial:
make -j1 all

# The original make target
all:
...
