Freescale 进行交叉编译ubuntu12.04 hf版本报错

使用的是IMX6开发板，系统是32位的ubuntu12.04，
在使用./ltib过程中，报错
arm-linux-gnueabihf-gcc: error: -mfloat-abi=soft and -mfloat-abi=hard may not be used together
还有就是busybox_unstripped uses VFP register arguments。

望指点

具体的错误是

当我不编译uboot和kernel时，执行./ltib -c,报错是

我也遇到该问题，
error: failed dependencies:

请问最后怎么解决的?
