[Buildroot] [PATCH RFC] Fix avr32 build using internal toolchain

[spdawson at gmail.com]

From: Simon Dawson <spdawson at gmail.com>

uClibc 0.9.31.1 fails to build for avr32 using recent (3.7.x) kernel
headers. The build failure looks like the following.

  CC libc/inet/if_index.os
In file included from /home/simond/TrainFX/code/git/third_party/buildroot.backports/output/toolchain/linux/include/linux/rtnetlink.h:6,
                 from libc/inet/netlinkaccess.h:34,
                 from libc/inet/if_index.c:36:
/home/simond/TrainFX/code/git/third_party/buildroot.backports/output/toolchain/linux/include/linux/if_link.h:291: error: expected specifier-qualifier-list before '__be16'

make[1]: Leaving directory `/home/simond/TrainFX/code/git/third_party/buildroot.backports/output/toolchain/uClibc-0.9.31.1'
make: *** [/home/simond/TrainFX/code/git/third_party/buildroot.backports/output/toolchain/uClibc-0.9.31.1/lib/libc.a] Error 2

This patch adjusts the system type definitions in the netlinkaccess.h
header, updating the types to match those used in uClibc 0.9.33.2.
