This has nothing whatsoever to do with cygwin.

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).
