i686 to c3-2 crosstool build fails on setjmp

[Simon Poole <simon dot armlinux at themalago dot net>]

I'm currently toying with taking advantage of the GCC -march=c3-2 option 
to correctly target one of our builds for the VIA C3-2.

Building crosstool-0.28-rc37 fails during the main Glibc build at setjmp.S.

I'm building with the following parameters on an i686-pc-linux-gnu build 
box:

BINUTILS_DIR=binutils-2.15
GCC_DIR=gcc-3.4.2
GLIBC_DIR=glibc-2.3.3
LINUX_DIR=linux-2.4.25
GLIBCTHREADS_FILENAME=glibc-linuxthreads-2.3.3
GCC_LANGUAGES="c,c++"
TARGET_CFLAGS="-O"
TARGET=i686-c3_2-linux-gnu
GCC_EXTRA_CONFIG=--with-arch=c3-2 --enable-cxx-flags=-march=c3-2

The failure looks like this:

Any advice on what steps to take?
* Have I done something wrong with my build setup?
* Should I be digging for a bug in GCC/glibc/binutils?
* Should I be using different package versions?
* Should I just forget about trying to cross-compile from i686 to c3-2?

Any advice appreciated...

Simon.
