 Replying to [comment:15 Peter_Dyballa@…]:

 > So this time it's the new (?) ld that fails, as it does with gcc48
 @4.8.4, see Ticket  https://trac.macports.org/ticket/46677. Maybe ld64
 should be chosen for the job… GCC49 @4.9.2 builds fine with the setting
 "port:ld64" in the depends_lib section.

 I was able to build '''libgcc @4.9.2_1''' on a PowerBook G4 by first
 explicitly choosing '''ld64 +ld64_97'''.  (By default, '''ld64''' installs
 with the variant '''+ld64_127''' on PowerBook G4's running Leopard.)  See
 the ticket https://trac.macports.org/ticket/46801 for the build logs for
 '''libgcc'''.
