This is probably just a copy of the ELF file. You probably have to 
perform the steps in bsps/powerpc/motorola_powerpc/config/mvme2100.cfg 
by hand:

define bsp-post-link
     $(default-bsp-post-link)
      $(OBJCOPY) -O binary -R .comment -S $(basename $@)$(EXEEXT) rtems
      gzip -vf9 rtems
      $(LD) -o $(basename $@)$(DOWNEXT) \
         $(PROJECT_RELEASE)/lib/bootloader.o \
         --just-symbols=$(basename $@)$(EXEEXT) \
         --no-warn-mismatch \
          -b binary rtems.gz -T $(PROJECT_RELEASE)/lib/ppcboot.lds \
          -Map $(basename $@).map && chmod 755 $@
      rm -f rtems.gz
