I've got ld compiled in debug mode right now.  I don't see the
problem here at first inspection, so I'm posting it so others can have
a look at it.  I'm trying to compile a kernel with the config file
(also included) and a single small modification (changing the kernel
to trigger serial at 4 instead of 8 on a 16550).
