And with gcc-4.4:
$ gcc-4.4 -o encutil.o -Os -fPIC -c encutil.i
$ readelf -r encutil.o
Relocation section '.rela.text' at offset 0x474 contains 3 entries:
Offset Info Type Sym.Value Sym. Name + Addend
0000005a 000005fc R_PPC_REL16_HA 00000000 .got2 + 8022
0000005e 000005fa R_PPC_REL16_LO 00000000 .got2 + 8026
00000078 00000b12 R_PPC_PLTREL24 00000000 SEC_ASN1Encode_Util + 8000
Relocation section '.rela.got2' at offset 0x498 contains 1 entries:
Offset Info Type Sym.Value Sym. Name + Addend
00000000 00000901 R_PPC_ADDR32 00000000 crmf_encoder_out + 0
