[second attempt with signed-off-by: in the patch header and
a better config here]

  This patch fixes the broken avr32 target in crosstool-ng. Mostly
that had to do with replacing the dead custom tarball at
dev.doredevelopments.dk (which entire site has dissapeared!) and
downloading the avr32-headers from Atmel directly, and adding .zip
extractor logic to handle it.

To configure it for avr32 after launching ct-ng menuconfig in an empty
directory:

       Paths and misc options ->
               Shell to use as CONFIG_SHELL = sh
       Target options ->
               Target Architecture = avr32
       Toolchain options ->
               Tuple's alias = avr32
       Binary utilities ->
               binutils version = 2.18a
       C compiler
               gcc version = 4.2.2
       C-library
               newlib version = 1.17.0
               Enable IOs on long long = yes
               Enable IOs on floats and doubles = yes
               Disable the syscalls supplied with newlib = yes

CONFIG_SHELL is necessary to get round the "fragment: command not
found" bug when binutils-2.18 is configured using bash.

Cheers

This patch fixes the download of the avr32 headers in crosstool-ng  by
fetching them directly from Atmel's web site instead of the now-broken URL
given by the original author of the avr32-header-fetching modification,
who fetched them from a copy on his own, now-defunct server.
