keyutils builds on neither avr32, nor microblaze (probably because
the toolchains used fot those archictectures are way too old), with:

    ..../microblazeel-unknown-linux-gnu-gcc -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE
    -D_FILE_OFFSET_BITS=64 -I. -DPKGBUILD="\"2012-12-27\"" -DPKGVERSION="\"keyutils-1.5.5\""
    -DAPIVERSION="\"libkeyutils-1.4\"" -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE
    -D_FILE_OFFSET_BITS=64  -pipe -Os  -g -Wall -Werror -UNO_GLIBC_KEYERR -o keyutils.o -c keyutils.c
    cc1: warnings being treated as errors
    key.dns_resolver.c: In function 'main':
    key.dns_resolver.c:690: warning: dereferencing type-punned pointer will break strict-aliasing rules

Fixing with -fno-strict-aliasing only partially solves the issue for these
two archs, since the C library does not export the resolver symbols so the
link fails down the road...
  - on microblaze, glibc-2.3.6 is tool old and does not set these symbols
    as GLOBALs;
  - on avr32, uClibc does not have these symbols.

It is much more easy to just disable keyutils for avr32 and microblaze.

Fixes both (avr2, microblaze):

Merry X-Mas!

PS. Thanks Richard for the help understanding those issues.
