GCC Patches for AVR32

Compiling GCC should be straight forward, follow the simple guide below:

1. Run ./configure with your favorite options. You probably need to include at least --target=avr32-linux

Now, you should be able to do the usual make and make install to build and install the toolchain.

Remember to fetch the latest config.sub and config.guess from http://git.savannah.gnu.org/gitweb/?p=config.git;a=tree if you get in trouble with unsupported architecture from the configure script.
