revolving to a previous MacPorts situation with Time Machine

[Renee Otten]

Hopefully this PR (https://github.com/macports/macports-ports/pull/33528) fixes the build issue for “glib2 +universal”. As I mentioned in the Trac ticket I have no way to test this personally so someone else who wants to do this on an amr64 machine should do some testing. 

Best, 
Renee
