At least portinstall doesn't touch MAKEFLAGS: insert something like
FOO!=echo -- ${MAKEFLAGS} >/tmp/A
into a port's makefile and call portinstall for than port:

MAKEFLAGS=-j2 portinstall ...

Would be strange if portupgrade would be different from portinstall. So 
nothing is broken that wasn't already.
