As reported by Thomas Petazzoni, the uclibc 0.9.31 build fails for avr32:
In file included from /opt/br-avr32-full-2013.11-rc1/usr/avr32-buildroot-linux-uclibc/sysroot/usr/include/linux/kernel.h:4,

make[1]: *** [libc/inet/if_index.os] Error 1
make[1]: Leaving directory `/opt/toolchain-build/build/uclibc-0.9.31.1'
The problem is reported at:
https://lkml.org/lkml/2013/5/18/1
The offending kernel commit is:
http://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=
ccdfcc398594
The fix is to patch uclibc 0.9.31 to add the missing kernel data types. The patch
will only be generated for avr32, since uclibc 0.9.31 is not available in Buildroot
for any other architecture.

+libc/sysdeps: add __kernel_long and __kernel_ulong
+
+Linux 3.4 added __kernel_long_t and __kernel_ulong_t and various
+exported header files were updated to use these new types. Add the
+definitions for __kernel_long_t and __kernel_ulong_t to the relevant
+kernel_types.h headers.
