If that's all you've been trying to achieve, it's trivial.

Configure binutils with --prefix=$SOMEWHERE then make && make install.

Configure gcc with --prefix=$SOMEWHERE then make && make install.

Just use the same $SOMEWHERE for binutils and gcc.

Then you can just run $SOMEWHERE/bin/gcc to use it, or add
$SOMEWHERE/bin to the start of your PATH to make it the default.
