powrpc-linux-gcc  version2.95.2, glibc2.1.3

powerpc-linux-gcc -D__ASSEMBLY__ -D__KERNEL__ -I/mpc_dvr/linux-2.4.25/include -I/mpc_dvr/linux-2.4.25/arch/ppc   -c -o cpu_setup_6xx.o cpu_setup_6xx.S
cpu_setup_6xx.S: Assembler messages:
cpu_setup_6xx.S:444: Error: Unrecognized opcode: `mftbl'
cpu_setup_6xx.S:445: Error: Unrecognized opcode: `mftbl'
make[1]: *** [cpu_setup_6xx.o] Error 1
make[1]: Leaving directory `/mpc_dvr/linux-2.4.25/arch/ppc/kernel'
make: *** [_dir_arch/ppc/kernel] Error 2

是powerpc-linux-gcc不识别mftbl命令？ 该如何挽救？ 谢谢
