Add new architechture in gcc build error

[daniel tian]

Hi,
   I have already finished CPU port named RICE.  The previous version
I did is on gcc 4.0.2. it can be compiled.  Now I wanna move it to
v4.3.0.  I added the config script just as the CRX architechture.
   But when run the configure,

export TARGET=rice-elf
export PREFIX=/usr/local/cross/$TARGET
export PATH=$PATH:$PREFIX/bin

rm -fr build-gcc
mkdir build-gcc

cd build-gcc
../rice-gcc-4.3.0/configure --target=$TARGET --prefix=$PREFIX
--enable-languages=c  --without-headers --with-newlib --with-gnu-as
--with-gnu-ld --disable-multilib --disable-libssp

make all 2>&1 | tee build.log



but the error occurred like the following:

I add the script in those files just like the CRX architechture:

I check the config.log, here is error:

the config.log file is attached in the mail.

Binutils is installed into the computer(Of course it has ported onto RICE).


I search the gcc maillist, but I can't find some useful information.
Can anybody give me some advice.

Thank you very much!
