trouble building gcc-3.2 --target=m68k-linux from scratch

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

I'm attempting to build a m68k-linux compiler from scratch using stock
versions of:

linux-2.5.1
binutils-2.13
gcc-3.2
glibc-2.2.5
gdb-5.2.1

building with bill Gatliff's script to config the kernel, copy over
the hears, config/binud binutils, config/build gcc-bootstrap...

The kernel headers copy over fine, binutils-builds, and gcc-bootstrap
is 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/gcc-3.2/configure --with-gcc-version-trigger=/home/pbarada/work/cvs-wavemark/cross-linux-tools/gcc-3.2/gcc/version.c --host=i686-pc-linux-gnu --target=m68k-linux --prefix=/tmp/junk --enable-languages=c --with-local-prefix=/tmp/junk/m68k-linux --without-headers --with-newlib --disable-shared --verbose --norecursion 
#  using "mt-frag"

And it fails building gcc/unwind-dw2.c:

/home/pbarada/work/cvs-wavemark/cross-linux-tools/gcc-3.2/gcc/gthr-posix.h:37:21: pthread.h: No such file or directory

Configure created ghtr-default.h with '#include <pthread.h>' since it
found a pthread.h that can be used, but that was by using the *host*
compiler to find a phtreads.h, not the *target* compiler.

Since a stock linux source doesn't have pthread.h in its headers, and
glibc hasn't been built yet, there's no pthread.h that can be used at
this time.

If I add --disable-threads to the configure for the bootstrap, it
completes.

1) Why does configure think that it has a valid pthreads.h(or that is
   should use the host compiler to find one)?
2) Is --disable-threads necessary for the bootstrap step?

All suggestions are appreciated...
