When compiling with this patch applied, I get the following error:

  Kernel: arch/arm/boot/Image is ready
    LD      arch/arm/boot/compressed/vmlinux
/home/albin/x-tools/arm-unknown-linux-uclibcgnueabi/lib/gcc/arm-unknown-linux-uclibcgnueabi/4.3.2/libgcc.a(_dvmd_lnx.o):
In function `__div0':
/home/albin/devel/free-electrons/toolchain/targets/src/gcc-4.3.2/libgcc/../gcc/config/arm/lib1funcs.asm:1079:
undefined reference to `raise'
make[2]: *** [arch/arm/boot/compressed/vmlinux] Error 1
make[1]: *** [arch/arm/boot/compressed/vmlinux] Error 2

I've got no idea where this symbol is defined, though. Has anyone an idea on
this ?
