It's the MacOS section though.

Can you replace "powerpc64" with "powerpc64%" in the Linux section?

  ifeq ($(strip $(filter-out powerpc64,$(target_cpu))),)
    ifneq ($(strip $(MULTISUBDIR)),/32)
      LIBGNAT_TARGET_PAIRS +=3D $(GNATRTL_128BIT_PAIRS)
      EXTRA_GNATRTL_NONTASKING_OBJS +=3D $(GNATRTL_128BIT_OBJS)
    endif
  else
    ifeq ($(strip $(MULTISUBDIR)),/64)
      LIBGNAT_TARGET_PAIRS +=3D $(GNATRTL_128BIT_PAIRS)
      EXTRA_GNATRTL_NONTASKING_OBJS +=3D $(GNATRTL_128BIT_OBJS)
    endif
  endif=
