Sadly there was no response to my previous email but I send this in the hope it be of any help to anyone like me. This problem was solved the other day and the main problem was I had a varaible _KERNEL_ defined for busybox building (from misunderstanding). So when I replace the kernel header (from the compiler's standard include path) it works just fine without rebuilding glibc.

So I looked up the internet and did 'make headers_install ARCH=.. CROSS_COMPILE=.. INSTALL_HDR_PATH=..'. Then I used the new header files instead of files under sparc-snake-linux/sys-include. But I had to copy over some missing files from the sys-include to the new header directories and had to copy some missiong definitions from the sys-include files to the corresponing file in the new header files. Is this what I am supposed to do? (why are there some missing files? Doesn't it work well for versions later than 2.6?) And do I have to build the glibc again with this new header files? (I'm using glibc for busybox) any help would be deeply appreciated.
