But that causes also the "all" to be run in not-parallel, because the
meaning of .NOTPARALLEL is:
If `.NOTPARALLEL' is mentioned as a target, then this invocation of `make' will be run serially, even if the
`-j'option is given.
It does not mean, as you appear to imagine, to run only the listed
prerequisites in not-parallel. That would be nice!
