Subject: [PATCH] trivial fix for i386 cross compile

Hi all,
I used to be be able to cross compile for i386 on my x86_64 machine,
but recently something (gcc/binutils?) changed, and it stopped working.
Following patch makes cross compile work with:
make ARCH=i386 CFLAGS_KERNEL="-m32" AFLAGS_KERNEL="-m32" bzImage
Without the patch I'm getting the following error:
SYSCALL arch/i386/kernel/vsyscall-syms.o
/usr/lib/gcc/x86_64-pc-linux-gnu/3.4.3/../../../../x86_64-pc-linux-gnu/bin/ld:
Relocatable linking with relocations from format elf32-i386
(arch/i386/kernel/vsyscall-sysenter.o) to format elf64-x86-64
(arch/i386/kernel/vsyscall-syms.o) is not supported
collect2: ld returned 1 exit status
Regards,
Tony
