I think I added this because both the mlguestfs.cma and mlguestfs.cmxa
targets generate libmlguestfs.a:

mlguestfs.cma: libguestfsocaml.a guestfs.cmo
        $(OCAMLMKLIB) -o mlguestfs \
          $(libguestfsocaml_a_OBJECTS) guestfs.cmo \
          -L$(top_builddir)/src/.libs -lguestfs

mlguestfs.cmxa: libguestfsocaml.a guestfs.cmx
        $(OCAMLMKLIB) -o mlguestfs \
          $(libguestfsocaml_a_OBJECTS) guestfs.cmx \
          -L$(top_builddir)/src/.libs -lguestfs

As far as I know, those are the only targets that shouldn't be run
parallel. 

I think that an extra target (mlguestfs.cmxa: mlguestfs.cma) would make
the .NOTPARALLEL unnecessary.
