GCC and the binutils are designed to work together, such that if you
configure both with the same --prefix option GCC will use the binutils
assembler.  Unfortunately I do not know of a way to tell GCC to use a
arm-linux-gnueabi-as assembler.

Download a GNU binutils release and see binutils/README.  It's pretty
much the same as building GCC.  Just make sure to use the same
--prefix and --target options for both GCC and the binutils.
