Comment (by kencu):

 the system python on BigSur is universal, so it can be done...MacPorts
 does not make it easy for ports to just use that, however.

 Some ports may use python to just process scripts; there is a way to avoid
 a universal python there by telling the Portfile to skip the architecture
 check in that case for that port.

 But others will need a real universal python, so that indeed seems to be
 the next hurdle.

 icu has been difficult to build universal for a while...and then we will
 tackle gcc...
