gcc-3.3.1-glibc-2.3.2-binutils-2.14 cross compile kernel problems

[hyding]

hi,
    I have built cross-toolchain with gcc-3.3.1, binutils-2.14,
glibc-2.3.2 and linux-2.4.18 header files. I have succeeded in compiling
a test program with gcc into a static app. This test program runs well
in the target. But i failed to build kernel with gcc. The info is as
follow:
