sudo port upgrade --enforce-variants installed +universal

...I think.

You can replace "installed" with particular port names, if you don't  
want to rebuild all installed ports.

Not all our ports can build universal at this time so you may  
encounter errors. If you do, please file tickets, if there aren't  
already any for those ports.
