Can't build m68k-linux gdb-5.2.1

[Peter Barada <pbarada at mail dot wm dot sps dot mot dot com>]

I'm trying to build a gdb for m68k-linux, configured as:

#!/bin/sh
# This file was generated automatically by configure.  Do not edit.
# This directory was configured as follows:
/home/pbarada/work/cvs-wavemark/cross-linux-tools/gdb-5.2.1/configure --host=i686-pc-linux-gnu --target=m68k-linux --prefix=/tmp/cross-tools --norecursion 
#  using "mt-frag"

And it won't link:

All the missing references are in gdb/m68klinux-nat.c, so I'd assume
this is supposed to be built, but isn't for --target=m68k-linux.  Does
anyone have any idea how I can get it to be built?

While I'm at it, how do I configure(and build) a gdbserver to run on
m68k-linux that's built on an x86-linux machine?

All help is appreciated.
