Portfiles should be able to say that they support a parallel build and
that they don't support a parallel build, i.e. you have 3 possibilities:
"yes" (which can later be changed to "no" if someone finds that it
doesn't work on some particular machine), "no" (that could be changed
to "yes" once the bug has been fixed upstream), and "don't know".
