 The changes here

 https://github.com/macports/macports-
 ports/commit/2453011ee18c25153b716a2ae42bed85ed52752a

 only remove the explicit reference to the classic liker option on the
 Macports for Xcode 16 or newer. Internally, GCC still knows about the
 option and uses it, and removing that will require an upstream GCC fix.
