Fix: restrict -ld_classic linker flag to Xcode 15.0.x only

  -ld_classic was added as a workaround for weak symbol crash (114813650)
  introduced by Xcode 15.0's new linker. This issue was resolved in
  Xcode 15.1, and -ld_classic is deprecated in Xcode 16 and removed
  in Xcode 26. Restricting the flag avoids build errors on newer Xcode
  versions and allows use of the faster new linker.
