You have to include $PREFIX/bin into your PATH.

Just keep it as --prefix=/usr/avr, and let it decide about the rest
by itself.

/usr does work.  All those things that are really different for the
cross compilation environment are installed unter a different name.
The only clashes I know of are related to documentation files and
perhaps internationalization (message catalogs).

Of course, your binutils should have been configured and installed using
the same prefix as your AVR-GCC.
