说明：使用busybox1.9.2来制作文件系统
交叉编译工具链：arm-none-linux-gnueabi-
arm-linux-

在编译内核时，已经开了eabi的支持。

Use the ARM EABI to compile the kernel

Allow old ABI binaries to run with this kernel (EXPERIMENTAL)

使用arm-linux-制作文件系统能正常挂载。

使用arm-none-linux-gnueabi-的交叉编译工具链制作文件系统，不能挂载。
提示信息为：

VFS: Mounted root (jffs2 filesystem) on device 31:2.
Freeing init memory: 148K
Front of /sbin/init! //此处为我在内核中添加的打印信息

内核中增加打印信息：
printk("Front of /sbin/init! \n"

;
run_init_process("/sbin/init"

;
printk("Back of /sbin/init! \n"

;
run_init_process("/etc/init"

;
printk("Back of /etc/init! \n"

;
run_init_process("/bin/init"

;
printk("Back of /bin/init! \n"

;
run_init_process("/bin/sh"

;
printk("Back of /bin/sh! \n"

;

在制作生成的busybox属性如下：
file bin/busybox
bin/busybox: ELF 32-bit LSB executable, ARM, version 1 (SYSV), statically linked, for GNU/Linux 2.6.14, stripped //eabi工具链编译的，不能挂载

bin /busybox: ELF 32-bit LSB executable, ARM, version 1 (ARM), for GNU/Linux 2.4.3, dynamically linked (uses shared libs), stripped //非eabi工具链编译，能正常挂载

各位大虾们，大家帮忙看看有什么解决的方法？为什么会出现这个问题？不胜感激！已经搞了一周了，没一点办法。
