Comment (by NicosPavlov):

 I could not confirm that it is actually the issue as I don't have an M1
 processor, but If you want to install an older version of gcc-devel, you
 can follow the procedure detailed in
 [https://trac.macports.org/wiki/howto/InstallingOlderPort:how to install
 older ports].
