Comment (by mopihopi):

 The buildbot has now successfully built libgcc-devel @13-20220911 for
 macOS 12 x86_64 (4 days after the update, so apparently there was a large
 backlog), although the [https://build.macports.org/builders/ports-
 12_x86_64-builder/builds/42086/steps/install-port/logs/main.log log file]
 shows that it used an older Xcode (13.2.1) and macOS (12.2.1).  (Oddly
 there is still no arm64 build even though its buildbot is idle.)  I was
 able to install the binary from the Xcode 13.2.1 buildbot for now to work
 around the Xcode 14.0 build failure.
