Following the merge of the nds32 architecture, two types of build
failures started to appear:

 - The target binutils package failed to build, because binutils does
   not yet have support for nds32. I tried with the latest binutils
   release, 2.32, and it was the same. So for now, I have disabled
   binutils on nds32. However, in binutils source, I see that
   bfd/elf-nds32.c is present, so there at least the beginning of some
   support. Could you comment on the status of nds32 support in
   binutils upstream ?

   Build failure: http://autobuild.buildroot.net/results/1b1/1b18acb11db4d6c4198deb7385aff3d4d524c37e/build-end.log

 - The libffi library does not have support for nds32 as well, so I
   made sure that we don't try to build configurations that include
   libffi on nds32. Are you planning on adding nds32 support to libffi
   upstream ?
