AVR32 toolchain reinstated

The AVR32 external source toolchain seems to work again using the gcc-4.2.2 compiler with patches from www.atmel.no/buildroot (revision 2.2.0-rc4).

After a small fix in libdaemon where libtoolize seems to replace the recently copied config.* from package/gnuconfig, the build of the atngw100 completes generating a linux, jffs2 and tar file systems, as well as u-boot.bin
