    Document some user-settable make variables in ports.7

    This is not a comprehensive list, as the variables themselves are spread
    out over multiple files, but it is a start.

    Add a section to make.conf noting that variables may be set there that
    affect ports builds, but refer to ports.7 and elsewhere for the actual
    listing; any listing in make.conf.5 would likely become out of date
    fairly quickly.
