Invoking gcc with "-march=native" should do exactly what you want with far less effort than rebuilding the toolchain from scratch (a task not for the faint of heart nor for the impatient). Make cares very little what architecture it runs on; binutils cares deeply but almost certainly does the right thing already. If you need more information, try 'man gcc' and 'http://gcc.gnu.org' (in that order).
