交叉编译powerpc64内核失败（unrecognised emulation mode:）

买柴火的小火柴 2015-05-16 07:23:14

我是使用buildroot构造交叉编译环境，配置时主要是使用自带的这个配置
qemu_ppc_mpc8544ds_defconfig，里面做了一点修改。

然后想交叉编译内核linux-3.18.4
使用的是这个配置 arch/powerpc/configs/mpc85xx_defconfig 将它复制到源码目录下，名字改成.config
然后就

# make ARCH=powerpc  CROSS_COMPILE=powerpc64-linux-

结果编译了一段时间，报错
