arch/avr32: Fix download of header files

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.

It also adds the necessary logic to extract from a zip file, as that is
how the headers are packaged.

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.

Prepared against crosstool-ng mercurial trunk on 31 March 2012.

     5     headers_install: fix __packed in exported kernel headers

     7     checkpatch.pl warns about using __attribute__((packed)) in kernel

     8     headers: "__packed is preferred over __attribute__((packed))". If one

     9     follows that advice it could cause problems in the exported header

    10     files, because the outside world doesn't know about this shortcut.

    12     For example busybox will fail to compile:

    13      CC      miscutils/ubi_attach_detach.o

    14      In file included from miscutils/ubi_attach_detach.c:27:0:

    15      /usr/include/mtd/ubi-user.h:330:3: error: conflicting types for ‘__packed’

    16      /usr/include/mtd/ubi-user.h:314:3: note: previous declaration of ‘__packed’ was here

    17     ...

    19     Fix the problem by substituting __packed with __attribute__((packed)) in

    20     the header_install.pl script.
