Try this :
- install linux headers in ${INSTALL_DIR}/arm-linux/include
- compile/install binutils
- gcc :

rm -rf ${BUILD_DIR}/gcc-3/libchill
rm -rf ${BUILD_DIR}/gcc-3/libf2c
rm -rf ${BUILD_DIR}/gcc-3/libio
rm -rf ${BUILD_DIR}/gcc-3/libobjc
rm -rf ${BUILD_DIR}/gcc-3/libstdc++

  ../gcc-3/configure --prefix=${INSTALL_DIR}  \
	--target=${TARGET_ARCH} --with-cpu=xscale \
	--program-transform-name=s,^,arm-linux-, \
	--without-fp --with-softfloat-support=internal --with-newlib --enable-languages="c" \
	--disable-threads --disable-shared --enable-static \
	--with-inhibit-libc \
	--with-headers=${INSTALL_DIR}/arm-linux/include
   		
make
make install

- compile glibc
- reextract gcc sources, configure like this :

  ../gcc-3/configure --prefix=${INSTALL_DIR} \
	--target=${TARGET_ARCH} --with-cpu=xscale \
	--program-transform-name=s,^,arm-linux-, \
	--without-fp --with-softfloat-support=internal --enable-languages=c,c++ \
	--enable-threads=posix \
	--with-headers=${INSTALL_DIR}/arm-linux/include
make
