Comment (by ryandesign):

 The muniversal portgroup currently defines a universal variant when you
 include it. It also defines procedures and options that relate to that
 universal variant. If you don't want a universal variant, don't include
 the portgroup. It's always been as simple as that.

 The simplest solution for your portfile is therefore to include the
 portgroup only if `${subport} ne "${name}-extra"`.

 If you want to change the behavior of the portgroup so that it does not
 define the universal variant if `${supported_archs} eq "noarch"`, that
 would require supported_archs to be declared before the portgroup is
 included. Portgroups are usually included at the top of the portfile, and
 in your portfile, you do include the portgroup before setting
 supported_archs.

 Your patch makes the portgroup's universal variant print an error if
 `${supported_archs} eq noarch`. That might be a reasonable safeguard to
 have in the portgroup, but it does not excuse the portfile from using the
 portgroup correctly. We don't usually want ports to have variants that do
 nothing but print an error.
