SubjectMore ARM binutils fuckage
There's not much to say about this, other than scream and go hide in the
corner. ARM toolchains are just basically fscked.

arm-linux-ld -EL -p --no-undefined -X -o .tmp_vmlinux1 -T
arch/arm/kernel/vmlinux.lds arch/arm/kernel/head.o
arch/arm/kernel/init_task.o init/built-in.o --start-group
usr/built-in.o arch/arm/kernel/built-in.o arch/arm/mm/built-in.o
arch/arm/common/built-in.o arch/arm/mach-versatile/built-in.o
arch/arm/nwfpe/built-in.o arch/arm/vfp/built-in.o kernel/built-in.o
mm/built-in.o fs/built-in.o ipc/built-in.o security/built-in.o
crypto/built-in.o block/built-in.o arch/arm/lib/lib.a lib/lib.a
arch/arm/lib/built-in.o lib/built-in.o drivers/built-in.o
sound/built-in.o net/built-in.o --end-group

Produces no error, but:

$ arm-linux-nm ../build/versatile/.tmp_vmlinux1 |grep ' U '
U __divdi3
U __udivdi3
U __umoddi3

Duh.

Result is you get successful kernel builds without any error, but a *bad*
incomplete image. IOW, you do not know whether or not your kernel is
_safe_ to execute.

That's binutils 2.17. binutils 2.16 had this problem and I tried to get a
patch into the kernel to use 'nm' to detect this fsckage. We *need* this
patch in the kernel.

Sam, can we resurrect my attempts to do this please?
