Hi There,

This patch intends to check value of --with-arch against the arm-arches.def,
rather than current solution that use hard coded things in config.gcc.
Tested with various values of --with-arch and it works. Is it ok to trunk?

BR,
Terry

     * config.gcc (arm*-*-*): Check --with-arch against arm-arches.def.
