"Error: bad register name %rbp" when building toolchain

[filosofo <lahughes at cisco dot com>]

I am trying to build a cross-compiler on linux for an x86 custom board using
crosstool-ng-1.2.2.
My build and host system is an AMD opteron linux 2.6.9 x86_64. I am trying
to build the crosscompiler for an Intel x86/386/686 multi-core cpu.

I am a complete newbie at this so please forgive anything seemingly
extraneous.

Here's the specs on the host compiler:
Reading specs from /usr/lib/gcc/x86_64-redhat-linux/3.4.6/specs
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man
--infodir=/usr/share/info --enable-shared --enable-threads=posix
--disable-checking --with-system-zlib --enable-__cxa_atexit
--disable-libunwind-exceptions --enable-java-awt=gtk
--host=x86_64-redhat-linux
Thread model: posix
gcc version 3.4.6 20060404 (Red Hat 3.4.6-9)

I've added a file with my crosstool configuration (crosstool.ma.config).

Here's the error (with context):

Thanks in advance for any insight here.
