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

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?
