The simplest way I know to achieve what you seem to want is to install binutils first, separately, to $PREFIX, then configure and install GCC to the same $PREFIX. During its configuration GCC will notice that binutils is installed in its final destination and will be configured to automatically use $PREFIX/bin/as and $PREFIX/bin/ld rather than the usual versions in your $PATH.
