You can put
  .NOTPARALLEL:

in a Makefile.am, and GNU make and some versions of BSD make will not
run things in parallel in this makefile.  HP-UX make won't obey, but it
has a different sytax other than -j anyway, and its parallel semantic
look fairly screwed up to me, at least some automake-generated rules
won't work with it.
