linux下编译交叉工具链的工具源码

The following fixes an error that occurs when building glibc-2.3.2 (but not glibc-2.2.5) for sh4:

It seems that the definitions in asm/user.h and the above patch collide.
I'm not sure why you need this patch, but is it needed for the problem
about struct ustat that you pointed out in this list, isn't it?
I found why I don't hit ustat problem - my local kernel tree includes
the following patch, though I can't recall about it.

Regards,
