I don't know how to fix this, but I just came to the exact same error with some
"plain vanilla" cross-compiler building process:

RedHat linux --> powerpc-eabi
binutils-2.13, gcc-3.2, newlib-1.10.0

Here is an overview of the script that I ran:

export TARGET=powerpc-eabi
export PREFIX=/home/compiler/somewhere
export PATH=${PREFIX}/bin:$PATH
mkdir ${PREFIX}
mkdir elsewhere
cd elsewhere

../binutils-2.13/configure --target=${TARGET} --prefix=${PREFIX} 2>&1 | tee
../configure-binutils.log
make all install 2>&1 | tee ../make-binutils.log

rm config.cache /* if not useful, this is at least harmless */

../gcc-3.2/configure --target=${TARGET} --prefix=${PREFIX} --without-headers
--with-newlib 2>&1 | tee ../configure-gcc.log
make all-gcc install-gcc 2>&1 | tee ../make-gcc.log

rm config.cache /* if not useful, this is at least harmless */

../newlib-1.10.0/configure --target=${TARGET} --prefix=${PREFIX} 2>&1 | tee
../configure-newlib.log
make all install 2>&1 | tee ../make-newlib.log

rm config.cache /* if not useful, this is at least harmless */

../gcc-3.2/configure --target=${TARGET} --prefix=${PREFIX} --with-newlib 2>&1 |
tee ../configure-gcc-full.log
make all install 2>&1 | tee ../make-gcc-full.log

I hope we can fix it!
