Cross compiling gcc for mipsel error [as: unrecognized option `-G']

I've compiled and installed the binutils to my /usr/local/ directory
and copied the uClibc and linux headers in there too.

Then I configured my gcc
../gcc-3.4.4/configure --enable-languages="c,c++,java" --prefix=/usr/local/majax --target=mipsel i486-linux-gnu
creating cache ./config.cache
checking host system type... i486-pc-linux-gnu
checking target system type... mipsel-unknown-elf
checking build system type... i486-pc-linux-gnu
checking for a BSD compatible install... /usr/bin/install -c

Do you have any idea why this "-G" option is not recognized ?
Do you think it could come from a bad placement of the headers or the library files ?
